My doctor told me I have to take a CAT scan. What is that and how is it done?

A CAT scan is a type of X-ray imaging procedure used to visualize internal structures of the body. It involves using a computer to generate images of cross sections of the body, usually taken from different angles. The images are then combined to create a 3D image of the inside of the body. This allows doctors to view organs and other structures in great detail.
