Computed tomography is a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (sometimes called slices) , of the body. A CT scan shows detailed images of any part of the body, including bone, tissue, organs and blood vessels. CT scan images are more detailed than standard x-rays.

You will be ask to lie on table that slides into the large, circular opening of the CT scanning machine. The x-ray beam moves in a circle around the body. The x-ray beam is obtained at different angles and sent to a computer. The computer displays the images on a monitor.

Some CT scans may require the use of a contrast material. Contrast is a substance taken by mouth or injected into an IV line that causes a particular organ or tissue to be seen more clearly. Some CT scans require contrast to be taken by mouth and injected into an IV line. Contrast exams usually require you to fast for a certain period of time prior to the examination.

CT scans may also be used to visualize exact placement of needles during biopsy and fluid drainage procedures.

You should consult your physician if you have any questions about your CT scan.
