What is a CT (or CAT) scan?

A CT or CAT scan is a procedure that makes a series of detailed pictures of areas inside the body, such as the chest, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography or computerized axial tomography.
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.
