TEST ACRONYMCT or CAT Scan
Computed Tomography (CT) Scan
Used diagnostically, the CT scanner takes a series of x-ray pictures, which are combined by a computer to create extremely detailed, cross-sectional images of your internal organs or other parts of your body that cannot be examined with conventional x-rays.
WHEN TEST WOULD BE PERFORMED
The scan is used to detect tumors, determine the stage of the disease and whether cancerous cells have spread, and find out about the effectiveness of cancer treatment. CT scans are also used to guide some types of biopsies (the removal of a small amount of tissue for examination to determine whether cancer is present). Common areas that may be scanned include the head, neck, chest, abdomen, pelvis, or an extremity.
Tumor detection, information on spread of disease as well as effectiveness of treatment is valuable information for your doctor in determining course of treatment.
Some people may be concerned about the amount of radiation they receive during a CT scan. It is true that the radiation exposure from a CT scan can be higher than from a regular x-ray. However, not having the procedure can be more risky than having it, especially if cancer is suspected. People considering CT must weigh the risks and benefits.
