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

A CT scan is a type of X-ray that uses computer technology to create images of the inside of your body. It’s often used to look at organs and tissues, including the brain, heart, lungs, bones, and abdomen. The CT scanner uses X-rays to take pictures from different angles. These pictures are then put together to form a 3D image.
