CT Scans

CT scans, also known as CAT scans or computerized tomography, are painless diagnostic tests that use specialized X-ray equipment and powerful computers to create cross-section images of the inside of the body or the head. CT scans provide more detail than conventional X-rays and can produce images of bone, soft tissue and blood vessels all at the same time. 

How to prepare for your CT scan

Before your CT scan

Be sure to mention the medications you take and ask if it is okay to take them before the test. If instructed, stop eating and drinking eight hours before your CT. If instructed, drink contrast (a liquid that improves the image) eight hours before your CT. The test takes 1–2 hours.

During your CT scan

You may be given contrast through an intravenous (IV) line or by injection. You will lie on a table. The table slides into the CT scanner. The technologist will ask you to hold your breath for a few seconds during your scan.

After your CT scan

The radiation you are exposed to during a CT scan is only slightly higher than from a regular X-ray, and it passes through you immediately. You are not “radioactive” following a CT procedure.

If you take Glucophage (Metformin), do not take it for the next two days. If you had an IV injection, you may need to urinate an extra time to eliminate the contrast from your system. If you drank oral contrast (a berry smoothie), it will be evacuated in your stool. Most patients do not experience any changes in bowel movement and a laxative is generally not needed.

After your CT has been reviewed by our radiologist, your personal physician will receive a report of the findings. You physician will then advise you of the results and discuss what further procedures, if any, are needed.
