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

A CT or CAT scan is an imaging technique used in radiology to produce cross-sectional images of the body. It uses a combination of X-rays and computer technology to create detailed pictures of organs, bones, and tissues inside the body. The patient lies on a table that slides through the scanner, which rotates around the patient while taking pictures. The pictures are then sent to a computer where they are interpreted by a radiologist.
