A computed tomography scan (CT scan or CAT scan) uses computer-controlled X-rays to create images of the body. An x-ray unit rotates around your body. The result is a three dimensional image of your insides.

A CT scan only takes seconds to perform.

Avoid Unnecessary Risk From Radiation

Too much radiation can increase the risk for cancer.  Decrease the risk by avoiding unnecessary CT scans, by asking questions, and by keeping a copy of each scan or other test in your Medical Binder. (Take your Binder each time you see a doctor. You never know what questions a doctor will ask or information that will become relevant at a given moment.)
