My doctor has recommended a CT scan, but I don't understand what it means. What should I do?

A CT scan is a type of medical imaging test that uses X-rays to create cross-sectional images of the body. It can help your doctor diagnose and evaluate many conditions, including cancer, stroke, heart disease, and trauma. The procedure takes about 30 minutes and involves lying still on a table while the machine rotates around you. You may feel some mild discomfort from the pressure of the machine.
