CAT scan (or CT scan) stands for Computerized Axial Tomography. It's a way of using a spinning x-ray and computer to make high-resolution images of the inside of your body. You lie flat on a table that moves through the machine quickly and takes many circular pictures. A computer then puts those pictures together to complete your exam. Any part of your body can be captured and a technologist instructs the CAT scan where to begin and end taking pictures. To enhance difficult to make out areas, some CAT scans are done after injecting you with a special contrast (dye) to clarify indistinct areas. You may also be asked to drink a mixture of contrast, which will highlight your stomach and colon.
