What do I need to know about a CT scan?

A CT scan is an X-ray exam that uses computer technology to create cross-sectional images of the body. It can be used to detect and diagnose many different types of diseases, including cancer, heart disease, stroke, and other illnesses. During the procedure, you will lie on a table that slides into the machine. The CT scanner rotates around you while taking pictures from different angles. You may feel some mild discomfort or nausea during the test, but it should not last long.
