Computed Tomography (CT) Scan Of The Spine: What Affects The Test
Content provided by Healthwise
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 lower back is needed, it should be done before any tests that use barium, such as a barium enema.
- 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.
- You are not able to lie still during the test.
