What is a CT Scan?

A CT scan is a diagnostic procedure that uses special x-ray equipment to obtain cross-sectional pictures of your body. The CT computer displays your pictures as detailed images of organs, bones and other tissues. This imaging technique is very detailed and provides your physician with a precise, clear picture.

CT scans are used for a variety of diagnostic purposes. They can help physicians detect tumors and blood clots in the head or other areas of the body. They can also diagnose cancer and other diseases throughout the body.

What to Expect

During a CT scan, you will lie on a table while it moves into the scanner. It’s important to keep still during the scan to ensure the most accurate images are recorded, and you may be asked to hold your breath at times. The technologist will leave the room but will be monitoring you at all times. Most exams take approximately 30 minutes.

The use of a contrast agent may be necessary for some patients in order to obtain a clear image.

How to Prepare

On the day of your scan, wear loose, comfortable clothing. Depending on the part of your body being examined, you may be asked to wear a hospital gown instead. All jewelry and eyeglasses will need to be removed. Some patients need to avoid fluid or foods before the test.
