CT scanning
On this page:
A CT scan is an imaging investigation using rays. It is performed on a specialised scanner which gives very detailed cross sectional images of the body. This helps us to look at your body more accurately than is possible using ordinary X-rays. The scanner consists of a ‘doughnut shaped’ structure, or gantry, about two feet thick with a hole in its centre, through which you pass while lying on a couch.
