What is a CT scan?
A CT scan is a Computerised Tomography scan. It uses X-rays, a scanner and computer equipment to take pictures of the brain, chest, abdomen, pelvis or spine.
It differs from a standard radiograph (X-ray) as it produces pictures in cross-section. Any or all parts of the body may be scanned depending on the patient’s condition.
What happens during a CT scan?
The patient must lie still during the scan, so this may require sedative drugs.
The scan table moves the patient through the scanner as the the scanner mechanism rotates around the patient’s head/body to take a series of images. A CT scan is a painless procedure and usually takes around 10 to 20 minutes to complete.
