– What is CT Scan?
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.
Types of CT Scan
We offer a wide range of ultrasound examinations. Please specify the area of concern when booking.
Your Appointment
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.
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.
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.
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.
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.
