Radiology Team
Administration and Clerical staff will greet you when you arrive at one of our reception areas. They will check that we have all your details and that they are correct, before booking you onto our computer system. They provide support, book appointments and answer queries.
Radiography Assistants/Helpers provide support to the radiologists, radiographers and nurses. They help patients prepare for their examination, for example getting you changed into a gown, giving you a drink before a CT scan or helping you to complete a questionnaire before your MRI scan.
Radiology Nurses help the team during interventional procedures, carry out selected interventional procedures independently and provide care and support for patients in the radiology department.
Assistant Practitioners have undertaken training to assist Radiographers with undertaking specific x-rays.
Diagnostic Radiographers employ a wide range of imaging techniques such as CT, MRI, Ultrasound and plain film to produce high quality images to diagnose injury or disease. Often, they interpret the images so that the correct treatment can be provided. They undertake diagnostic work and independent reporting as part of the multidisciplinary team. They are a key part of the delivery of acute as well as community-based services. Early diagnosis is a vital step in care pathways and the delivery of any subsequent treatment. Health surveillance screening such as mammography has a very important role to play in the early detection of cancer
Radiologists are doctors who are specially trained to interpret diagnostic images such as x-rays, MRI and CT scans. If you have an interventional procedure (such as a biopsy) a radiologist will perform the procedure. Ultrasound scans may be performed by a radiologist.
An electronic report of the results of your examination is made available for your doctor. This may be completed by a Radiologist or Advanced Practice Radiographer. -
Plain Film X-Ray
What is an x-ray?
X-rays are used to gain a diagnostic image of your bones and certain parts of the body. The x-ray beam is passed through the body part being examined and is read by a detector which sends the image to a computer.
How do x-rays work?
X-rays work by using electro-magnetic radiation to create images of the inside of your body.
When you get an x-ray a machine sends a beam of x-ray photons through our body. Different tissues absorb different amount of x-rays so the image shows variations in density.
Having an x-ray
X-rays are carried out by radiographers, who are healthcare professionals trained to use imaging technology, including X-ray machine.
When you attend for your x-ray you may be asked to remove any jewellery or clothing that may interfere with the image. You might also need to get changed into a gown.
You will be positioned by the radiographer to get the best image. They may ask you to hold still or take a deep breath and hold it for a moment.
The radiographer will move the machine around you and capture images at different angles.
Is there any associated risk?
The radiation dose that you get from an x-ray is very small and the risks are minimal.
Our staff consider both the risks and benefits when deciding what examination is best for you.
The benefits of having the x-ray will outweigh any risk.
There is naturally occurring radiation all around us called background radiation. It comes from various sources like the sun, rock and soil. We are exposed to this call the time, but it’s at a low level and generally considered safe.
The background radiation equivalent of some common x-ray examination are detailed below.
Background equivalent radiation times
Examination UK background equivalent radiation time. Skeletal Survey 3 weeks L-spine complete 3 days Abdomen AP 1.5 days Pelvis AP 5 days C-spine Complete 2 days T-spine Complete 2 days Chest X-ray 2 hours Extremity 2 hours Every effort is made to keep the radiation dose as low as possible.
Sensory Experience
A sensory room is a specially designed environment that caters to the sensory needs of the patient. A sensory room offers a safe space for children and adults with autism, dementia and other special needs to be x-rayed in a calm and quiet environment suitable to their individual needs.
Please ask a member of staff if you feel that this sensory environment would benefit a service user during their visit
Friends and Family
If you feel more comfortable, one person may accompany you for your appointment. In certain cases this person may be permitted into the examination room. But only if essential.
X-ray staff are unable to look after your children whilst you have your examination. Please make alternative arrangements or have another adult to accompany you.

Dental X-Ray
What is a Dental x-ray?
Dental X-rays are used to gain a diagnostic image of your teeth and jaw bone. The x-ray beam is passed through the body part being examined and is read by a detector which sends the image to a computer.
How do dental x-rays work?
Dental X-rays work by using electro-magnetic radiation to create images of the inside of your body.
When you get a dental x-ray, a machine sends a beam of x-ray photons through your body. Different tissues absorb different amounts of x-rays so the image shows variations in density.
Having a dental x-ray
Dental X-rays are carried out by radiographers, who are healthcare professionals trained to use imaging technology, including X-ray machine.
You may be asked to remove any jewellery or clothing that may interfere with the image.
You will be positioned by the radiographer to get the best image.
Depending on the dental image requested you may asked to either
- Stand still in the equipment whilst holding on to hand grips and the x-ray tube will rotate round your head to take the image (Panoramic) OR
- Sit in a dental chair and a small x-ray detector will be placed in your mouth and the x-ray machine is then positioned in front of your face to take the image (Single). You may already had one of these done in the dentist
Is there any associated risk?
The radiation dose that you get from a dental x-ray is very small and the risks are minimal.
Our staff consider both the risks and benefits when deciding what examination is best for you.
The benefits of having the x-ray will outweigh any risk.
There is naturally occurring radiation all around us called background radiation. It comes from various sources like the sun, rock and soil. We are exposed to this call the time, but it’s at a low level and generally considered safe.
The background radiation equivalent of some common x-ray examination are detailed below.
Typical effective doses, equivalent periods of natural background radiation and lifetime fatal cancer risks from diagnostic dental medical exposures.
Diagnostic procedure Typical effective doses (mSv) Equivalent period of natural background radiation 1 Lifetime additional risk of fatal cancer per examination 2 Teeth (single) < 0.01 < 1.5 days 1 in a few million Teeth (panoramic) 0.01 1.5 days 1 in 2 million Every effort is made to keep the radiation dose as low as possible.

Ultrasound
What is Ultrasound?
An ultrasound scan uses high-frequency sound waves. These waves create an image of the part of your body being scanned.
This is done by using a small hand-held device called a transducer and gel, which is moved over the surface of the skin and uses the sound waves to create a picture.
The scan usually takes 15-30 minutes depending on what part of your body is being scanned, and how much information we need to get.
The scan is performed by a Sonographer or Radiologist who specialises in Ultrasound.
Ultrasound scans are a very safe procedure. They can help to:
- make a diagnosis
- make a decision about your treatment
- monitor a condition
- monitor the progress of a pregnancy
We have a specialist team of staff to make your ultrasound scan a pleasant experience
Preparation
Depending on the area been examined and information required some scans do not require preparation but for others it is important to follow the instructions in the letter.
Please check your appointment letter for the department your scan is being performed in and any preparation required for your scan.
You should take all your medicines as normal.
You should allow at least 1 hour in the ultrasound department.
You may need to remove some items of clothing if they are covering the area being examined so you might want to wear something that is easy to remove.
Students or trainees might be there for your scan. If you do not want them there, please ask. It will not affect your care.
You can ask the sonographer or radiologist any questions at any time before, during or after your scan.
Patient experience
You will be called to the scan room by one of our assistants or the sonographer and prepared for the scan.
You will be asked to lie on the examination couch and some clear water-based gel will be applied to your skin and the sonographer or radiologist will slowly and gently move the transducer over your skin to examine the area indicated.
They will view the images produced on a screen.
The room will be dimly light so that they can view the screen more clearly.
Records of the images will be made so they can be viewed later.
You cannot feel ultrasound waves however, it is important we get a clear image so the sonographer or radiologist might need to press down on the probe, and this might feel uncomfortable. You may be asked to hold your breath, take a deep breath or move position to help get clearer images.
If you are finding it difficult, please tell the sonographer or doctor
If a second opinion is needed, this can increase the time it takes.
After your ultrasound scan
Once the scan has finished, the gel is wiped off and you can get dressed.
In most cases, you can leave the hospital straight away or go back to the ward if you are staying in hospital.
The gel is not harmful but it is advisable to wash your skin with soap and water as soon as is convenient to prevent skin irritation.
Results of your ultrasound scan
The results will be sent to the doctor who referred you for the scan.
If you are an inpatient, the results will normally be available to the ward doctor on the day of your scan.
If it was your GP or a consultant that referred you, the results will normally arrive with them within 1 week. Please be advised some reports may take longer than 1 week.
Antenatal reports will be placed in your maternity notes at the end of the ultrasound scan.
Cancelling or changing your appointment
If for any reason you need to cancel or change your appointment, please let us know as soon as possible. This allows us to reschedule you for another time and helps to prevent wasted appointments.

Ultrasound (Fetal Anomaly Scan)
Introduction
Ultrasound scanning is now an integral method of assessing your baby inside the womb. It has been used for many years and there has been no evidence of harmful effects to the fetus or mother. It is important that you read this information carefully before attending for your Anomaly Scan.
Anomaly Scan
It is recommended that a detailed scan of your baby be performed around 19 -20 weeks gestation as the main organs can usually be well seen then.
The scan is performed by a skilled Sonographer (a radiographer who has been trained in Obstetric ultrasound)
The main objectives of the examination are to check:
- the findings of any earlier scan
- that your pregnancy is progressing normally and,
- that the main organs of the baby appear normal.
The scan will be performed to ensure that the maximum amount of information possible is obtained.
One adult may accompany you to your scan. The mid-pregnancy scan can sometimes find problems with the baby, so you may like someone to come with you to the scan.
Children are not allowed to attend the Fetal Anomaly Scan appointment.
Recording of scan is not permitted. Mobile phones are to be switched off and please do not bring cameras or video cameras.
How is the Scan Performed?
You will be asked to lie on a couch and expose your lower abdominal area. Some gel is placed on the skin to aid the movement of the ultrasound probe over the abdomen. Occasional pressure may be applied. Moving images are displayed on a screen and “still images” allow measurements to be made.
What Does The Examination Include?
A routine examination takes up to 30 minutes. Areas checked during the scan include the baby’s:
- heart
- head and brain
- spine
- arms and legs
- stomach
- kidneys and bladder
- abdominal wall and placenta site
- the amount of amniotic fluid
These areas will be pointed out to you on the screen during the scan. The position of the baby can present challenges in obtaining the required views and the heart in particular requires detailed assessment.
The Sonographer therefore needs to concentrate silently on the image and this does not mean that a problem has been detected. A series of measurements are recorded to compare the gestational age with the due dates established at the booking scan. If there is an area of the baby which is difficult to visualise, the sonographer may ask a colleague to scan also.
There may be occasions when a further scan is required to see an area more clearly if, for example, if the baby is in a position where not all its parts can be examined fully or the mother has a high BMI.
Fetal Gender at the time of the anomaly scan
If you and your partner would like to know the gender of the baby, please ask the sonographer at the beginning of your scan.
A verbal opinion only will be offered by the sonographer at the time of the Fetal Anomaly scan. Regional Guidance does not permit the sonographer to write down the fetal gender.
Occasionally, the sonographer will not be able to tell, usually because of the position of the baby. If it is not possible to determine fetal gender, you will not receive another screening ultrasound for that purpose.
You should be aware that Fetal Gender assessment of a baby is not 100% accurate. The sonographer will only tell you the sex of the baby if you want to know that information.
Results
The sonographer will be able to tell you the results of the scan at the time.
A picture of your baby is provided. This image is a personal record only and is not used for diagnostic purposes.
Consent
The choice to decline or have the Fetal Anomaly scan and/or subsequent scans/tests is up to you and you can decline or stop the process at any stage.
If you give consent to have the scan performed, by attending the appointment it will be assumed that you will want to be informed about any problem or potential problem identified on the scan.
If you do not consent to have the scan performed, please inform us that you will not be attending for your appointment by phoning the number on the front of this leaflet.
What if an Abnormality is Suspected?
If an abnormality is detected or suspected, the Sonographer may ask another member of staff to look at the scan for a second opinion. The Sonographer will to the best of their knowledge discuss the findings with you and also explain the Referral pathway, should you be referred to a specialist who may work in another hospital.
This can depend on the type of abnormality detected.
The referral will be made immediately by the Sonographer.
Unfortunately not all problems can be identified using ultrasound. Currently it finds around two thirds of physical problems and one third will not be seen.
This means that even if your scan is normal, there is still a small chance that your baby could have a problem. There are also some conditions that develop later in pregnancy and these will therefore not be seen at the time of the scan.
Below is a list of different types of congenital problems, and how likely scanning is to identify each problem.
Conditions Detection Rate (%) Anencephaly 98 Open spina bifida 90 Cleft lip 75 Diaphragmatic hernia 60 Gastroschisis 98 Exomphalos 80 Serious cardiac anomalies includes the following: Transportation of the Great Arteries (TGA)
Atrioventicular Septal Defect (AVSD)
Tetralogy of Fallot (TOF)
Hypoplastic Left Heart Syndrome (HLHS)
50 Bilateral renal agenesis 84 Lethal skeletal dysplasia 60 Edward’s syndrome (Trisomy 18) 95 Patau’s syndrome (Trisomy 13) 95 Points to consider before deciding to have the Fetal Anomaly Scan:
- This information refers only to the Fetal Anomaly scan.
- This scan is voluntary. You can choose to have the scan done or not.
- Make sure you understand all the information you have received about the scan.
- About two thirds of major problems and some minor problems may be detected and it is important to remember that a normal scan cannot give 100% guarantee of your baby’s condition.
- It is assumed that if you have the scan performed, you will want to know if a problem has been detected.
- Some problems may require special management and/or delivery which can only be organised if the problem is known.
This is an exciting stage of your pregnancy but you may also be feeling slightly apprehensive.
We hope this information will answer some questions you may have.

Computerised Tomography (CT)
What is a CT scan?
A Computed Tomography, or CT scanner, uses X-rays to obtain detailed pictures of your body in cross sections, or slices. These pictures are examined by a Radiologist (a medical doctor who specialises in reading X-ray images) and the report is made available to your Consultant or Specialist.
What happens before the scan?
For a CT scan of your Abdomen or Pelvis you will be given water, or a special liquid to highlight the bowel, to drink an hour before your scan.
For some scans we may need to give you an injection of X-ray dye (contrast medium), and for this we will place a small plastic tube (cannula) into a vein in your arm or hand before the scan. You will be asked a number of questions prior to the X-ray dye injection. Please bring a list of all the medications you are taking with you.
You may be asked to change into a hospital gown. If you wear loose fitting clothing without metal fasteners you may not need to change.
If we are scanning your head then earrings, hair clips, hearing aids, metallic dentures etc. will need to be removed.
What happens during the scan?
The CT scanner looks like a large doughnut. You will need to lie on a motorised bed which moves slowly through the centre of the “doughnut” while the pictures are taken. You will need to lie still to avoid blurring the images and you may be asked to hold your breath for a moment.
If you receive X-ray dye during your scan, it may give you a warm feeling throughout the body and a metallic taste in your mouth. These sensations pass in a couple of minutes.
Depending on which part of your body is being scanned, the scan will typically take between 5 and 15 minutes.
The scanner is not noisy and the procedure should not be painful.
The Radiographer who performs the scan can see and hear you at all times via a connecting window and intercom.
Are there side effects or risks from the procedure?
As with X-rays, CT scanning involves radiation but the amount is kept to a minimum by sophisticated dose controls on the scanner. We are all exposed to background radiation from the ground, building materials and air every day. CT gives you an additional dose (typically equal to the natural radiation we receive from the atmosphere over a period of approximately 3 years), but the benefits of the scan are thought to outweigh any risks. It is important to have the scan performed so a diagnosis can be made and any necessary treatment planned.
Female patients who are, or might be pregnant must inform a member of staff in advance.
Are there any risks with the injection?
The X-ray dye that is used contains Iodine which shows up well in CT scans and increases the amount of information obtained. It is very safe and usually causes nothing more than a warm feeling passing around your body. However as with any medicines some people can react to it. You will be asked about any previous allergic reactions to Iodine or X-ray dye, or any other allergies.
Occasionally the X-ray dye can leak outside the vein and cause temporary swelling and discomfort. This is unlikely to happen, but if it does we will give you further instructions and advice.
Person of child bearing potential from the ages of 11-55 inclusive
CT scans of the Abdomen or Pelvis must be performed within 10 days of the start of a menstrual period. If your appointment is outside this period, and there is any chance of you being pregnant, please telephone for another appointment. If you don’t contact us, you may be reappointed and sent away without being scanned.
What happens after your scan?
You can go home soon after the scan. You can eat and drink as normal and resume your usual activities straight after the scan.
If you have had an injection of X-ray dye we will ask you to wait for 15 or 20 minutes before you leave the department to ensure that you are feeling okay and there is no sign of any reaction to the dye you have been given. You will be asked to increase your fluid intake for the next day or two. If you are a diabetic taking Metformin we will speak to you about the possible need to stop taking it for 48 hours after the scan.
How will I get my results?
You will not be given any results on the day of your scan.
The images will be studied by the Radiologist and the report made available to the person who sent you for your scan.
Your Hospital Consultant/Specialist will send you an appointment to attend the relevant clinic or you will be contacted by letter with the results. If you do not hear anything about the results within a few weeks, we suggest you telephone the referring doctor’s secretary for advice.

MRI
What is an MRI scan?
Magnetic Resonance Imaging is a safe modern scanning technique that uses strong magnetic fields to produce very detailed images of parts of the body. Computer systems are used to help make the images.
What are the benefits of an MRI scan?
An MRI scan can help to find out what is causing your problem and help your doctor to find the best treatment for you. An MRI scan provides much more detailed pictures of your body than an ordinary x-rays. It is particularly good at identifying problems in the spine, the brain and blood vessels. It is also helpful for looking at other parts of the body, often when other types of scan have not given a full picture. Unlike x-rays and CT (computerised tomography) scans, MRI scans do not use radiation.
Prior to coming for your scan
When you confirm your appointment, you will be asked to inform us if you have any of the following items in or on your body.
FAILURE TO INFORM US MAY RESULT IN DELAYS OR STAFF BEING UNABLE TO PROCEED WITH YOUR SCAN WHEN YOU ARRIVE
- Pacemaker, cardiac devices, stents
- Aneurysm clips, neuro stimulator or programmable shunt
- Any recent surgeries
- Any Gastric surgery (gastric sleeve/gastric band)
- Any OGD’s/Colonoscopy’s
- Any implanted devices within the body e.g. joint replacements/ring pessary
- Any injury to the body or eyes involving metal
- Any medicated skin patches or pumps delivering medication
- Any silver dressings on wounds
- Any tattoos/piercings
Medicated skin patches must be removed immediately before your scan. Seek advice from your GP in advance to ensure your treatment is not affected. Please bring a replacement patch.
Diabetic monitors must be removed immediately before your scan. Please bring a replacement monitor and if necessary seek advice from your GP in advance to ensure your treatment is not affected.
Is there any other preparation?
Usually there is no special preparation for an MRI scan. You may eat and drink normally before and after the scan unless you have been told otherwise on your appointment letter.
What happens when I come for my scan?
You will complete a checklist with a radiographer and depending on some answers; x-rays may be required before your scan.
You will be asked to change into a hospital gown and remove all metal objects for example all piercings, hair clips, hair extensions, jewellery, money, keys, credit cards, mobile phones hearing aids etc. Lockers are provided for your valuables.
You can wear your glasses but these will be removed immediately before the scan.
Do I need an injection?
For some scans we may need to give you an injection of dye (contrast medium) or muscle relaxant, and for this we will place a small plastic tube (cannula) into a vein in your arm or hand before the scan. You will be asked a number of questions prior to the injection. The muscle relaxant is usually used for abdominal and pelvic examinations. This is to improve the quality of the scan. All instructions will be on your appointment letter, please read it carefully.
What happens during the scan?
You will need to lie on a motorised bed which moves the body part being examined slowly to the centre of the scanner during the examination.
At certain times the scanner will make loud knocking noises. This is normal and you will be given ear plugs and headphones to wear to reduce the noise and music will be played through these for extra comfort. It is extremely important to stay still during the scan. A buzzer will be given to you. If you feel unwell or are unable to tolerate the scan, this can be pressed and a radiographer will come in to the room to you. The Radiographer who performs the scan can see and hear you at all times via a connecting window and intercom.
Depending on which part of your body is being scanned, the scan will typically take between 20 and 30 minutes. However, some examinations may last up to 1 hour.
Patients from the ages of 11-55 inclusive
It is important to tell the radiographer if you are, or may be pregnant prior to the scan as steps can be taken to check if the scan is still necessary. At present, there have been no reported effects from MRI to the unborn child, however as a precaution we advise against scanning in the first trimester.
What happens after your scan?
You can go home soon after the scan. You can eat and drink as normal and resume your usual activities straight after the scan.
If you have had an injection of dye we will ask you to wait for 20 minutes before you leave the department to ensure that you are feeling okay and there is no sign of any reaction to the dye you have been given. You will be asked to increase your fluid intake for the next day or two.
How will I get my results?
You will not be given any results on the day of your scan.
The images will be studied by the Radiologist and the report made available to the person who sent you for your scan.
Your Hospital Consultant/Specialist will send you an appointment to attend the relevant clinic or you will be contacted by letter with the results. If you do not hear anything about the results within a few weeks, we suggest you telephone the referring doctor’s secretary for advice

Nuclear Medicine
What is Nuclear Medicine (NM)?
A Nuclear Medicine scan is a medical speciality which is used to diagnose illnesses or disorders in a safe and painless way. NM refers to a medicine (a pharmaceutical) which is attached to a small quantity of radioactive material (a radioisotope). The combination is called a Radiopharmaceutical. There are many different Radiopharmaceuticals available to study various parts of the body, and which one is used depends on the condition to be diagnosed or treated. The Radiopharmaceutical is designed to go to a specific place in the body where there could be a disease or abnormality.
The amount of the Radiopharmaceutical given to a patient is very low and is just sufficient to obtain the information needed before it begins to break down and decay. The radiation dose received is medically insignificant. The patient experiences no discomfort during the test and after a short time there is no trace that the test was ever done. The non-invasive nature of a NM scan, together with being able to view an organ functioning from outside the body, makes this imaging technique a great diagnostic tool.
How does it work?
A special camera (a gamma camera) takes images of tissues and organs in the body after the Radiopharmaceutical is administered to the patient either by injection, taking a tablet or breathing in a gas. The Radiopharmaceutical emits gamma rays which the gamma camera detects and it works with a computer to produce an image that the doctor can view. A NM scan shows the activity and function of the tissues or organs and is an effective way to view and document abnormal metabolic activity in the body.
Pregnancy and Breastfeeding
Because a Nuclear Medicine scan involves receiving small amount of radioactivity, you must tell us if you are, or think that you might be pregnant, or if you are breastfeeding. If possible, tell us as soon as you receive your appointment or as soon as you arrive in the Nuclear Medicine Department.
It is OK however, to have a Lung Perfusion scan if you are pregnant, as the doctor may think it is necessary to exclude a blood clot.
For all Nuclear medicine scans we will check for pregnancy or breast feeding before we administer any Radiopharmaceutical
Do you need to do anything?
You need to contact the Nuclear Medicine department if you:
- Work with photographic or other radiosensitive material
- Are pregnant/breast-feeding (see above)
Are there any precautions I should take?
The injection has no side effects. However, because of the radioactive nature of the substance, we would recommend that you:
- Drink plenty of fluids.
- Flush the toilet twice after use.
- Avoid prolonged (over 30 minutes) close contact with those who are pregnant.
- Do not allow small children to sit on your knee for longer than 30 minutes.
These instructions last for 12 hours
Are there any risks involved?
The radiation dose that you will receive, and its associated risks are low. The Doctor who has requested that you have the scan, will consider both the risks and benefits before deciding this scan is appropriate for you.
When will I get the results?
You will not get the results on the day of your scan. The results will be sent to your Consultant or doctor who arranged the scan and they will be discussed with you at your next appointment.

DEXA (DXA)
What is a DXA (Dexa) scan?
A DXA scan is a unique type of scan that measures how much bone tissue you have. This is called your bone mineral density (BMD).
DXA stands for ‘Dual Energy X-ray Absorptiometry’. It is the gold standard for measuring bone mineral density.
A DXA scan is one of the most accurate ways to diagnose or assess someone’s risk of Osteopenia or Osteoporosis. Osteoporosis is a condition that weakens bones and makes them more likely to fracture (break). This condition can happen at any age although is more common as we get older. You will have been referred for this by a doctor or specialist nurse or dietician who has assessed your risk for osteoporosis.
What does having a DXA scan involve?
A DXA scan is the most effective scan available to identify low bone mineral density.
Your appointment will take approximately 20-40 mins and a specialist radiographer will take your scan. They will be able to talk to you throughout the scan and answer questions you may have. Your weight and height will be measured.
You will lie on a scanning table and the scanning arm will move over your body. There are no enclosed spaces or tunnels. There are no injections. It is a quick and painless scan. Areas that can be scanned are your lower spine, your hip and your forearm as these are good areas for reliable measurements.
For the spine scan you will have a sponge placed under your knees to raise them. For the hip scan you will have a small, plastic frame placed between your feet to allow for proper positioning of your leg. You need to stay still when the scan is taking place. This is needed to stop blurry images and is just a short part of the appointment. You can go home when the scan is done.
DXA scans use low dose X-ray radiation. The amount of radiation is small in relation to what we receive in our daily lives, for example from natural background radiation or from time spent flying on board an aircraft. The associated risks are minimal or negligible.
Measuring bone
During a DXA scan, X-rays will be passed through your body. Some radiation will be absorbed by the bone and soft tissue, and some will travel through your body.
Special detectors in the DXA scanner measure how much radiation passes through your bones, and this information is sent to a computer.
Your bone density measurements will be compared with the bone density of a young adult of your own age, gender and ethnicity. The difference between these measurements is known as a T-score. This will not be available immediately after your scan.
Is there any preparation required?
You can eat and drink as normal as there is NO Preparation for this examination. Please continue with your normal medication.
When you receive your appointment, please contact the department to confirm your attendance and also to inform us of any mobility issues.
Clothing
Please wear loose fitting clothing. Avoid zips, buttons, metal hooks, belts, braces and under-wired bras if possible.
How do I get results?
If you have been referred by a GP, your results should be available from your health centre within 10-14 days.
If you are attending the Fracture Liaison Service, a specialist nurse will contact you about your results within 4-6 weeks.
If you have been referred by a consultant, a dietician or a specialist nurse your results will be available to them within 7-10 days.
Patients of child bearing potential:
This scan must be performed within 28 days of the 1st day of your last menstrual cycle.

Fluoroscopy
What is Fluoroscopy?
Fluoroscopy is an imaging modality that uses x-rays to allow real-time visualization of body structures. During fluoroscopy, x-ray beams are continually emitted and captured on a screen, producing a real-time, dynamic image. This allows for dynamic assessment of anatomy and function.
Standard X-rays are like photographs, whereas fluoroscopy is like a video.
Healthcare providers use fluoroscopy for two main purposes: for diagnostic purposes and to help guide certain treatment procedures (known as Interventional Radiology)
Why do I need a fluoroscopy test?
Your healthcare provider may recommend a fluoroscopy test if they want to check the function of a particular organ, system or another internal part of your body. You may also need fluoroscopy for certain medical procedures that require imaging guidance, such as surgery or stent placements.
What is a Fluoroscopy test used for at Altnagelvin?
Diagnostic fluoroscopy
- Barium swallows and meals
- Water soluble contrast enemas
- Defecating Proctograms
- Cystography including Paediatic Micturating Cystograms
- Hysterosalpingograms
- Fluoroscopic guided joint injections
- Arthrography
- Angiography
Fluoroscopy for procedure guidance
Fluoroscopy is also used to guide certain treatment procedures in Interventional Radiology and other areas of the hospital:
- Cardiac catheterization and PPCI
- Catheter insertion and manipulation
- Placement of stents, (Cardiology, Urology and Endoscopy)
- Orthopaedic surgery
Do I need to do anything to prepare for a fluoroscopy test?
Your preparation will depend on the type of fluoroscopy procedure and why you’re getting it. Some procedures don’t require any special preparations. For others, your provider may have you avoid certain medications and/or fast (not eat or drink anything except water) for several hours before the imaging procedure.
In any case, your provider will let you know if you need to do any special preparations.
If you’re pregnant or there’s a chance you may be pregnant, it’s important to let your provider know. Radiation from fluoroscopy can be harmful to a developing foetus.
If your fluoroscopy procedure involves contrast dye, it’s important to let your provider know if you have any allergies or have had issues with contrast dyes in the past.
What should I expect during a fluoroscopy test?
Depending on the type of procedure, you may have your fluoroscopy exam in the main radiology department or as part of your stay in a hospital, in another theatre or treatment area. For most fluoroscopy procedures, you can be awake during it. For other procedures, such as ones that involves surgery, you will go under general anaesthesia so that you’re asleep during the surgery.
Your fluoroscopy may include some or most of the following steps:
- You may need to remove any clothing and/or jewellery that may interfere with the procedure. If you need to remove clothing, your radiographer will give you a hospital gown.
- You may need to fast ahead of your fluoroscopy exam. Instructions of any fasting times and requirements will sent to you from the radiology department at the time of appointing.
- Some fluoroscopy procedures require a contrast dye, which is a safe substance that makes a part of your body show up more clearly on an X-ray. If this applies to you and your procedure, you will either drink a liquid containing contrast dye, your provider will insert a contrast dye liquid into your vein through an IV or your provider will insert the liquid through an enema, which is a procedure that flushes the dye into your rectum.
- The radiographer will then have you lay on an X-ray table. Depending on the type of procedure, you may be asked to move your body in different positions or move a certain body part. They may also ask you to hold your breath for a brief period.
- If your procedure involves getting a catheter, your provider will insert a needle in the appropriate body part. This may be your groin, elbow or another area.
I understand fluoroscopy procedures use x-rays, are the x-rays harmful to me?
X-rays can be harmful but the doses used in fluoroscopy are kept as low as possible. It is however, necessary to use x-rays to perform most of the aforementioned procedures safely. The radiology team will only use x-rays when absolutely necessary and use the lowest possible amount to minimise your exposure to radiation.

Interventional Radiology
What is Interventional Radiology (IR)?
Interventional Radiology (IR) is arguably one of the fastest growing specialties of modern medicine.
There are many descriptions of IR used, such as Radiology surgery, pinhole surgery and image guided surgery. They are all describing the same thing which is essentially a range of minimally invasive procedures that rely on imaging to precisely target an area for therapy or diagnosis, in a theatre type setting. Many of these procedures would historically have been performed with open surgery requiring general anaesthetic and a long hospital stay post-op. Nowadays the IR team can do many of these procedures as day cases or short stay.
How does it work?
Interventional Radiology procedures usually involve guiding a needle into the body using ultrasound or CT and accessing a particular organ (liver, kidney, stomach etc) or a vessel (artery or vein), then guiding a wire and catheter through the needle into that area. Using a real-time x-ray camera (fluoroscopy), the wire and catheter can then be guided through the body to perform whatever procedure is required.
What are the benefits of Interventional Radiology?
Most of our procedures are low risk, with minimal pain and a short recovery period.
What is Interventional Radiology used for at Altnagelvin?
We perform both planned and emergency procedures. We can:
- Take samples of tissue to diagnose cancer (biopsy)
- Relieve blockages eg. to the kidneys, bile ducts, bowel and blood vessels
- Drain fluid or pus
- Place feeding tubes
- Place dialysis lines
- Place Central Venous Access Devices and lines (like PICCs and Port’s)
Who makes up our team?
- Interventional Radiologist: A highly skilled clinical doctor who performs image-guided procedures. They also interpret the imaging to plan and monitor response to treatments.
- Nurses: IR nurses care for patients throughout their time in the department. They ensure patients are ready for procedures, give necessary medication and assist doctors during the procedure.
- Radiographers: Radiographers are specialists in medical images, providing imaging control for procedures.
- Anaesthetic team: Most IR procedures are performed with local anaesthetic or light sedation. However, general anaesthesia is sometimes needed for more painful or complex procedures.
Do you need to do anything?
Only procedures requiring sedation or a general anaesthetic require you to be “nil by mouth”. You should be informed of this when referred for a procedure or in your appointment letter.
It’s important that we check your blood results to ensure it’s safe to proceed with your procedure. We sometimes have to repeat blood tests on the day of your procedure. It is often necessary to insert a cannula (a small plastic tube into a blood vessel in the arm/hand) in case we need to give you any medications.
I understand Interventional Radiology procedures use x-rays, are the x-rays harmful to me?
X-rays can be harmful but the doses used in interventional procedures are kept as low as possible, but it is necessary to use x-rays to perform most procedures safely. The radiology team will only use x-rays when absolutely necessary and use the lowest possible amount to minimise your exposure to radiation.
If you’re pregnant or there’s a chance you may be pregnant, it’s important to let your provider know. Radiation from fluoroscopy can be harmful to a developing foetus.
