What is a CT Scan?
CT scan is a computerized axial tomographic
scan. A CT scan uses special X-ray equipment
to produce an image that is a cross section
or a slice of your body. When you are looking
at or “reading” a CT scan film,
think of the patient like a loaf of bread
and the image like one slice from that loaf.
CT scans can be used tp help diagnose
a variety of medical conditions, including
cancer, vascular disease, and cirrhosis.
Depending on a patient's symptoms, the CT
scan may be performed on different areas
of the body.
