CT/CAT scan patient guide

“My doctor says I need a CT/CAT scan. What do I need to know?”

Visit our e-health library to learn more about CT/CAT scans.

A CT/CAT (computed tomography) scan provides multiple views of internal organs and tissue by combining x-ray and computer technology. This scan can show your physician different body angles, and shows different types of body tissue.

You may be asked not to eat or drink anything prior to the test.

Patients must lie on a table that moves through a large round cylinder.

Contrast material is used with this test. You may be asked to swallow water or contrast material, or it may be injected, depending on type of scan.

You may be asked to put on a robe that will be provided to you by our center.

The test takes between 10 and 30 minutes. You will need to lie still for that length of time, but the test is not painful for most patients.

A radiologist will read and interpret the results of your scan and send a report to your physician. Your physician will share the results with you in a few days.

If you are scheduled for a CT scan with IV contrast, you must have only clear liquid beginning four hours prior to your appointment. After your appointment, please drink plenty of fluids.

If you are scheduled for a CT scan of the pelvis or abdomen, please visit Community Imaging Centers at least one day before your appointment. You will receive two bottles of oral contrast (barium) and instructions on when to take them.
