What is a C.T.?
A computed tomography (CT) scan is a special type of X-ray that can produce detailed pictures of structures inside the body. A CT scan is also called a computerized axial tomography (CAT) scan. Watch the video demontration below for a demonstration of a CT scan.
A CT scanner directs a series of X-rays through the body that are analyzed by a computer to produce a detailed picture of a "slice" of an organ or area being studied. Each X-ray pulse lasts only a fraction of a second, and it takes only a few seconds for the machine to record each slice. A CT scan produces clearer pictures of internal organs (such as the liver) than regular X-rays do. Information from a CT scan can be saved and stored on a computer for further study. Photographs of selected views can also be made.
Dense tissues, such as bones, appear white in the pictures produced by a CT scan. Less dense tissues, such as brain tissue or muscles, appear in shades of gray. Air-filled spaces, such as in the bowel or lungs, appear black.
