Description of the test
A computerized tomography scan (CT or CAT scan) is a test that produces a series of X-ray images of the body. The CT scanner passes X-rays through the body and produces cross-sectional pictures so each picture is a "slice" of the body. The images can be combined by a computer to create three dimensional images of internal organs and body structures.
The CT scan produces images that are more detailed than conventional X-ray films. Compared to plain X-rays, CT scans allow doctors to better detect and localize abnormalities of the various organs and tissues of the body using extremely accurate images.
