Description
How the Test is Performed
The test is done in the following way:
• You'll likely be asked to change into a hospital gown.
• You lie on a narrow table that slides into the center of the scanner. Once you are inside the scanner, the machine's x-ray beam rotates around you.
• You must be still during the exam, because movement causes blurred images. You may be told to hold your breath for short period of time.
The complete scan takes 30 seconds to a few minutes.
