CT / CAT Scan

A CT or CAT scan is a noninvasive, painless medical test that helps physicians diagnose and treat medical conditions. The CT combines the use of x-rays with computers to produce images that allow physicians to look inside a patient's body.

A CT can produce clear, extremely detailed pictures of the body's internal structures (colon, lung, heart, vessels) in a series of thin slices. The CT can differentiate bone from muscle and fat in the part of the body being examined.

CT Imaging is:

• one of the best tools for studying the chest and abdomen because it provides detailed, cross-sectional views of all types of tissue.
• often the preferred method for diagnosing many different cancers, including lung, liver and pancreatic cancer, since the image allows a physician to confirm the presence of a tumor and measure its size, precise location and the extent of the tumor's involvement with other nearby tissue.
• invaluable in diagnosing and treating spinal problems and injuries to the hands, feet and other skeletal structures because it can clearly show even very small bones as well as surrounding tissues such as muscle and blood vessels.
• an examination that plays a significant role in the detection, diagnosis and treatment of vascular diseases that can lead to stroke, kidney failure or even death.

Some CT studies require a contrast agent to enhance the pictures that are taken of your body. You will receive special instructions if your exam requires you to consume an oral contrast agent (barium sulfate) in advance. Certain studies may require you to have an IV Contrast (iodine injection).
