My doctor wants to do a CT scan on my chest. What is a CT scan?

A CT scan (Computed Tomography Scan) is an imaging procedure that uses X-rays and computer technology to produce cross-sectional images of the body. It can be used to help diagnose many different conditions, including cancer, heart disease, and stroke. The images produced by the CT scan are called slices. Each slice is made up of many pixels, which are tiny squares that make up the image.
