What Affects the Test

The following may stop you from having the test or may change the test results:

• Pregnancy. CT scans are not usually done during pregnancy.
• Barium and bismuth used for another test. These substances show up on a CT scan. If a CT scan of the belly is needed, it should be done before any tests that use barium, such as a barium enema.
• You are not able to lie still during the test.
• Metal objects in the body. These items, such as surgical clips or metal in joint replacements, may prevent a clear view of the body area.
