Introduction

A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body.  

CT scans are sometimes referred to as CAT scans or computed tomography scans.

They're carried out in hospital by specially trained operators called radiographers and can be done while you're staying in hospital or during a short visit.
