Computed tomography (CT) or computed axial tomography (CAT) scanning is a special non-invasive x-ray test that produces cross-section images of the body. Special x-ray equipment combined with sophisticated computers produces multiple images of the inside of the body.
 
These are viewed on a computer monitor allowing manipulation of the data to create 3-D and multi-planar images. 64-slice CT technology makes use of 4x as many detectors as a typical multi-detector CT scanner. This results in much improved image quality with remarkable speed. Detailed pictures of any organ are produced in a few seconds thus reducing motion artefact.
 
This technology has allowed special investigations such as coronary CT to image the coronary arteries of the heart and CT colonography or virtual colonography.
