My doctor wants to do a CT scan on my chest. What is a CT scan?

A computed tomography (CT) scan is a type of medical imaging test that uses x-rays to create cross-sectional images of the body. It’s often used to diagnose and treat a variety of conditions, including cancer, heart disease, stroke, and trauma. During the test, the patient lies on a table that slides into the scanner. The patient then undergoes a series of x-rays as the table moves through the machine. The resulting images are then reconstructed into detailed pictures of the body's internal structures.
