CT scan

A CT (computer tomography) scan is an X-ray examination where an X-ray tube, encapsulated in a ring, revolves around the patient lying on an immobile table. This allows hundreds of thin ‘cross-section images to be taken of the patient. These are subsequently uploaded to a powerful computer that can generate the images in any desired direction.

Examples

There are CT scans for different parts of the body. There are CT scans for the chest, abdomen, cranium, lumbar spine, cervical spine, sinusses, mastoid sinuses, arthoscopy, knee/pulse/shoulder/elbow/hip, angiogram of the neck arteries, angiogram of the coronary arteries, angiogram of the aorta and a virtual colonoscopy (Maria Middelares Medical Centre campus)...
