My doctor wants me to have a CT scan. What is the procedure like?

The CT scan is a medical imaging technique that uses X-rays to create cross-sectional images of the body. It is used to diagnose and treat many conditions, including cancer, heart disease, stroke, and other neurological disorders. The procedure involves lying still on a table while an X-ray machine rotates around you. You may be asked to hold your breath or stay very still during the scan.
