– What is CT Scan?

Three-Dimensional Precision Imaging

A computed tomography (CT) scan uses a series of X-ray beams taken from multiple angles around the body. A computer then combines these into detailed cross-sectional “slice” images — and by stacking hundreds of slices, produces highly accurate three-dimensional reconstructions of internal anatomy.

CT provides exceptional detail of bone, blood vessels, and solid organs, and is particularly useful for detecting tumours, pulmonary embolism, aortic aneurysm, and complex fractures. Modern low-dose protocols minimise radiation exposure while preserving image quality.

Some CT scans require the use of intravenous contrast (iodine dye) to enhance the visibility of blood vessels and certain tissues. Where contrast is required, our team will assess your suitability beforehand and advise on fasting requirements.

Your scan is carried out at one of our partner hospitals, in Surrey or central London, whichever is most convenient for you. Booking starts with a short telephone consultation with one of our GPs (£20, redeemable against the cost of your scan), who will check the test is right for you and arrange your referral. We then book your appointment at your preferred hospital and confirm the details with you directly.

Types of CT Scan

Areas We Can Image

We image a wide range of areas by CT. Please specify the area of concern during your telephone consultation.

Chest

Lungs, pleura, mediastinum, pulmonary arteries (PE protocol) and aorta

Abdomen & Pelvis

Liver, kidneys, pancreas, bowel, adrenal glands and pelvic organs

Head & Brain

Stroke assessment, head injury, sinus disease and intracranial pathology

Spine

Cervical, thoracic and lumbar spine; disc herniation, spinal canal stenosis

Coronary calcium score

Quantifies calcification in the coronary arteries as a cardiac risk marker

Angiography

Detailed imaging of blood vessels including carotid arteries, aorta, renal and peripheral vessels

Your Appointment

What to Expect

Telephone consultation & referral

Start with a 10-minute telephone consultation with one of our GPs (£20, redeemable against the cost of your scan). They’ll discuss your symptoms and history and, if the scan is appropriate, refer you and arrange it at your preferred partner hospital in Surrey or central London.

Pre-Scan Preparation

Depending on the scan type, you may need to fast for 4 hours. If contrast is required, we will check kidney function and allergies in advance. Remove metal objects and change into a gown.

Contrast Cannula

For contrast studies, a small cannula is placed in a vein in your arm. The contrast injection causes a warm flushing sensation for a few seconds, which quickly resolves.
You lie on a motorised table that passes through a large ring-shaped scanner. The process typically takes 5–15 minutes. You may be asked to hold your breath briefly for chest imaging.

Your results

Your scan is reported by a consultant radiologist, and the written report is emailed directly to you, usually within 3–5 working days of your test and often within 24 hours. If you’d like to talk the results through, you can book a follow-up GP consultation (from £60).

How do I book?

Booking starts with a short 10-minute telephone consultation with one of our GPs (£20, redeemable against the cost of your scan). They’ll check the scan is right for you and arrange your referral, then book it at your preferred partner hospital in Surrey or central London. We confirm all the details with you directly.

Is a CT scan claustrophobic?

The CT scanner is a large, open ring rather than a long enclosed tunnel — it is substantially less claustrophobic than an MRI. Most patients tolerate it without difficulty. If you are particularly anxious, please let our team know when booking and we can discuss strategies such as keeping your eyes closed and using breathing techniques to help you feel comfortable.

What does the contrast injection feel like?

When contrast is injected, most patients experience a warm flushing sensation that spreads through the body — this is normal and passes within 15–30 seconds. You may also notice a metallic taste briefly. A small number of patients experience mild nausea. Serious allergic reactions are rare, and we have protocols to manage these safely.

Can I eat before my CT scan?

This depends on the scan type and whether contrast is required. Abdominal/pelvic CT scans with contrast typically require 4 hours of fasting. Head and limb CTs without contrast generally require no fasting. When you book, our team will give you specific preparation instructions tailored to your scan type.

What is a CT coronary calcium score?

A CT coronary calcium score is a quick, low-dose CT scan of the chest that quantifies the amount of calcium deposited in the coronary arteries. It is a powerful marker of cardiovascular risk — the higher the score, the greater the risk of a future cardiac event. The scan takes around 10 minutes, requires no contrast, and is frequently used in executive health screens and preventive cardiology assessments.

How does CT compare to MRI?

CT and MRI complement each other — they are superior in different situations. CT is faster, better for bone and vascular imaging, and more accessible for urgent situations. MRI provides superior soft tissue contrast and uses no ionising radiation, making it preferred for brain, spinal cord, muscles, and joint imaging. Your clinician will recommend whichever modality best answers the clinical question.

Where will my scan take place?

At one of our partner hospitals, in Surrey or central London, whichever is most convenient for you. Once your GP has referred you, we arrange the appointment and confirm the location, date and time.

Can I discuss my results with a doctor afterwards?

Yes. Your written report is emailed directly to you, usually within 3–5 working days and often within 24 hours. If you’d like to go through what it means and any next steps, you can book a private GP consultation (from £60).
