Computed tomography (CT), or CAT scan, uses X-rays to obtain images of the body. CT scans are highly useful for examining injuries and abnormalities, guiding needle biopsies and aiding in surgical preparation. During the procedure, the patient is positioned on a table on his or her back, side or stomach, and may be provided with pillows for comfortable support. The table moves very slowly through the doughnut-shaped CT scanner. The X-ray beam inside the CT unit spirals slowly around the patient on all sides, creating 360-degree images or "slices" of the area being examined. As the patient moves through the unit, many slices are captured. The images are then combined to produce a highly detailed, three-dimensional digital image.
