CT Scan - Short for computed tomography, a CT scan is an X-ray procedure that uses a computer to generate three-dimensional, cross-sectional images of the body. In some cases, a CT scan can show diseased tissue and other affected areas that conventional X-rays may miss. CT scans are frequently used in cancer diagnosis and treatment to pinpoint the location of cancerous cells in the body. A CT scan is also known as a computed axial tomography scan, or CAT scan.
