CEA Scan

You have been scheduled for a CEA scan, which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects.

Preparation for the procedure:
We ask that you drink plenty of fluids on the day prior to the study. You will also be asked to drink plenty of fluids for twenty four hours after the injection. Please inform the technologist if you are pregnant or breast feeding. The imaging may be changed, or special instructions given based upon that information.

What to expect:
Once in the injection room you will be intravenously injected with a radioactive tracer and asked to return two and a half  to three hours later for the scan. Once in the scan room you will be lying down on a table and a camera with two or three detectors will rotate around you and make three dimensional images of your abdomen and pelvis. The scan takes approximately forty minutes. Following this another forty minute scan will be obtained of your body from head to pelvis. Claustrophobia is not usually a problem. You will need to return about forty five minutes later for an additional three dimensional image of your abdomen. This image takes about forty minutes. You may need to return the next day for the same imaging. This will take about ninety minutes.

The images will be reviewed and the results will be sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
