A computed tomography (CT) scan is a computer-assisted X-ray test that uses special equipment to create cross-sectional images and detailed views of the inside of your body. Organs, brain, lungs, tissues, bones and blood vessels may be examined with a CT scan.

The CT scan is a test used to diagnose conditions such as stomach and bowel problems, lung and kidney conditions, stroke and certain types of cancer.

The CT scan is a test provided by the Medical Imaging Department.
