<human>: My doctor wants me to get a CT scan. What is a CT scan and why is it important?
<bot>: A CT scan (Computed Tomography Scan) is an imaging test that uses X-rays to create cross-sectional images of your body. It can help doctors diagnose many different conditions, including cancer, heart disease, stroke, and other health problems. The images are used to look for abnormalities in the body’s soft tissues, bones, and organs.
