CT Scan
CT (computed tomography) is a specialised imaging test that uses X-ray beams to create detailed cross-sectional pictures of the body. It gives doctors a clear and accurate view of what’s happening inside your body, aiding with accurate diagnosis.
What is a CT scan?
A CT (computed tomography) scan is a procedure where a narrow X-ray beam rotates around the body. A computer collects the X-ray data and converts it into many thin cross-section images (slices), which together form a detailed 3D view of the internal structures of your body.
The scan is usually quick, typically taking less than 15 minutes, although the exact time it takes depends on which part of the body is being scanned and whether a contrast dye is used.
A CT scan is used when more detail is needed than a standard X-ray can provide. Some common reasons include:
assessing suspected fractures or bone injuries
investigating trauma to organs (for example, to the brain, chest, or abdomen)
evaluating tumours or lesions
examining lung disease, pulmonary issues, or vascular conditions
planning or monitoring treatment (such as surgery or radiotherapy)
guiding interventions (for example, CT-guided biopsy)
At Welbeck, we also offer cone beam CT (CBCT) for high-resolution imaging of the sinuses, skull base, and dental structures.
At Welbeck, all CT scans are performed in our state-of-the-art Imaging & Diagnostics centre, using advanced technology designed for both accuracy and safety. Our scanners feature Smart Dose technology, which automatically adjusts the radiation level to capture high-quality images while keeping radiation exposure as low as possible. This ensures every scan is safe, precise, and tailored to each patient.
We also use Spectral Technology, an advanced imaging system that enhances contrast and detail, helping our specialists detect even subtle tissue changes or lesions with exceptional clarity. Together, these innovations give our radiologists the most accurate insights possible – helping guide diagnosis, treatment, and your road to recovery.
Paediatrics
We offer appointments to paediatric patients aged 12 to 18. For full information on our paediatrics service, please visit our main Paediatrics page.
More information
Before your scan, your radiographer will explain the procedure and how long your scan is expected to take. Our modern CT machines are exceedingly fast – the whole chest can be scanned during a single breath-hold.
When you arrive, you’ll be asked to change into a gown, and once you’re ready, you’ll be shown to one of our scanning suites.
During the scan:
you’ll lie on a comfortable motorised bed that moves through the CT scanner
you’ll need to remain still while the X-ray tube (which is shaped like a doughnut) rotates around you
you may be asked to hold your breath for short periods if your scan involves the chest, abdomen, or brain
Sometimes, a contrast dye is needed to help the radiologist when interpreting the scan. If you need a contrast dye, it’ll be injected into a vein in your arm – you may feel a warmth or a metallic taste, but these effects are harmless and usually wear off quickly.
CT scans involve ionising radiation, which carries a small risk. At Welbeck, we use Smart Dose technology, which automatically adjusts the radiation level to capture high-quality images while keeping radiation exposure low. This ensures every scan is as safe as possible.
Contrast dye is generally safe, but in rare cases, allergic reactions or kidney effects may occur.
Before your scan, your radiologist will explain the procedure and answer any questions you have. You should let the radiology team know if you’re pregnant, have kidney problems, or have any allergies (especially to contrast dye).
You may be asked to fast for a few hours before the scan if contrast dye is to be used. Just before your scan, you’ll be asked to change into a hospital gown and to remove jewellery, watches, or metallic objects that could interfere with imaging.
You can usually go home or resume your normal activities immediately after your scan, and you’ll be able to drive yourself home if you wish. If a contract dye was used, it’s recommended to drink plenty of water to help flush it out.
One of our expert radiologists will interpret your images and prepare a report for your specialist, who will discuss it with you in a follow-up appointment.

Frequently asked questions
CT scans are generally avoided during pregnancy because the X-rays involve a small amount of radiation, which could pose a risk to your baby. In some urgent cases, your consultant may recommend a CT scan using the lowest possible radiation dose and protective shielding during pregnancy. If you’re pregnant or think you might be, always tell your care team before your scan. At Welbeck, your safety and wellbeing always come first, and our specialists will discuss all safer imaging alternatives, such as ultrasound, if appropriate.
Contrast dye is used when your consultant needs to see certain parts of your body in greater detail – for example, to highlight blood vessels, detect inflammation, or identify tumours. Not every CT scan requires contrast, and if you have allergies or kidney problems, your radiologist will assess whether it’s right for you.
Your scan images are reviewed by one of our consultant radiologists, who prepares a detailed report for your referring clinician. At Welbeck, we prioritise quick, accurate reporting so you have answers without unnecessary delay. Your team will let you know when you can expect your results, and this is often within hours or days, especially in urgent cases.
CT scans use X-rays to create detailed images of your body, while MRI scans use strong magnetic fields and radio waves instead of radiation. CT scans are usually quicker than MRI scans and do not involve being inside a tube like MRI scans, as the CT scanner is shaped like a doughnut that passes over you. Your consultant will recommend the most suitable scan based on your symptoms and medical history. At Welbeck, we offer both CT and MRI imaging on-site, so your care remains seamless.
