Computed Tomography
(CT scan)
CT is a noninvasive test that combines x-rays and computer scans. A computer combines the images to create views that more easily diagnose problems like cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders.
As a Patient:
-
If instructed, drink contrast (a liquid that improves the image) 1 1/2 hours before your CT.
-
The test may take 10 minutes to 2 hours, depending on whether contrast is used and the part of the body being scanned.
-
Arrive on time to check in, you may be asked to change into a hospital gown.
-
You may be given contrast through an intravenous (IV) line or by injection.
-
You will lie on a table. The table slides into the CT scanner.
-
The technologist will ask you to hold your breath for a few seconds during your scan.
-
After your test, you can go back to your normal diet and activities right away. Any contrast will pass naturally through your body within a day.
