Abnormal Head CT Scan
What is a CT Scan?
A 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.
