A CT (or CAT) scan uses x-rays to make cross-sectional images of your body. A CT image typically is thought of as a slice and allows the radiologist to look inside the body. Unlike a regular x-ray, a CT image provides detail for internal organs, soft tissues, and blood vessels.
How to Prepare for Your Test
- Depending on your exam, you may be required to withhold eating and drinking. The Diagnostic Imaging Department will contact you with specific instructions before your scan.
- Many CT scans require the use of a contrast agent to make parts of the body visible on the scan. Depending on your exam, a contrast agent may be injected or the contrast agent may be swallowed as a drink.
- Depending on your exam, you may be required to have blood work completed prior to the CT scan.
- Prior authorization may be needed for your CT scan.
- Women should always inform their physician and technologist if there is any possibility that they are pregnant. Another type of test may be recommended.
A radiologist will analyze the images and send a signed report to your primary care or referring physician, who will discuss the results with you.
