A computed tomography (CT) scan uses X-rays to make detailed pictures of parts of your body and the structures inside your body. During the test, you will lie on a table that is attached to the CT scanner. The CT scanner is a large doughnut-shaped machine.
Doctors use CT scans to study areas of the body, such as the brain, chest, or belly. CT scans are also used to assist or check on the success of a procedure or surgery. An example of this is when a CT is used to guide a needle into the body during a tissue biopsy.
Talk to your doctor about all your health conditions before the test. For example, tell your doctor if:
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
