My doctor wants to do a CT scan, but I'm not sure what it is. Can you tell me more?

A CT scan (also called a CAT scan or CT scan) is a type of X-ray exam that uses computer technology to create cross-sectional images of the body. It can be used to diagnose and treat many different types of medical conditions. The CT scan creates detailed pictures of the body's internal structures, including bones, organs, blood vessels, and soft tissues. It is often used to look for signs of disease or injury, as well as to help guide treatment decisions.
