My doctor says I should get a CT scan. How does a CT scan work?

A CT scan is an imaging test that uses x-rays to create cross-sectional images of the body. It’s used to detect tumors, cysts, and other abnormalities in the body. The CT scanner rotates around the patient while they are lying on a table. This allows the scanner to take many x-ray images from different angles, creating a three-dimensional picture of the body.
