What Happens During a CT Scan?

This test is done in a hospital or radiology office by a radiologist or technician. You'll lie on a narrow table that slides into the center of the scanner. Dye may be injected into a vein in your hand or arm.

The technician will let you know if you’ll need to change position, lie still, or hold your breath. When the test is done, you can go back to your normal activities.
