Computed Tomography (CT), also known as a CAT scan, is a sophisticated imaging technique that shows different levels of the anatomy. During CT imaging, the x-ray source rotates around the patient. Each rotation produces a single cross-sectional "slice", like the slices in a loaf of bread. These cross-sectional images are far superior in detail than standard x-rays and greatly enhance a physician's diagnosis.

CT scans are used to diagnose many conditions. This exam can evaluate abnormal masses, showing the size and shape of a tumor, its precise location and whether it's solid or hollow. In addition, CT scans can provide valuable information in the detection of abscesses, strokes, head injuries and bleeding inside the skull.
