Overview of Computerized Tomography (CT) Scans

Preparing For A CT Scan

The preparation needed for a computerized tomography scan can differ depending on what part of an individual's body is being scanned. While metal objects like jewelry, hair clips, zippers, studs, button snaps, and underwires do not pose a safety hazard during this type of scan, they can compromise the quality of the results. Some medications may need to be stopped before the scan because they can interfere with the contrast agent being used. 

When an individual has a computerized tomography scan on their abdomen or pelvis, they may need to consume a contrast drink before the scan so their digestive tract shows up clearly. Someone having a scan on their pelvic region may need to have an enema with a contrast substance to help highlight their bowels on the scan. They may be asked to empty their bladder before the scan. A contrast agent may need to be injected into a patient's bloodstream before the scan.
