What is a CT (or CAT) scan?

Computerized tomography (CT), sometimes called a CAT scan, is a special type of cross-sectional x-ray generated by a computer. The result is a more detailed image than a conventional x-ray. When used in cancer diagnosis, CT scans are typically used to pinpoint a tumor deep in the brain, lungs, liver, pancreas, adrenal glands, and bones.
