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

A CT scan is a type of medical imaging procedure that uses x-rays to create cross-sectional images of the body. It’s used to diagnose and treat a variety of health problems, including cancer, heart disease, and stroke. During a CT scan, a series of x-rays are taken from different angles around the body. The images are then reconstructed into a 3D image that can be viewed on a computer screen.
