If your doctor refers you for a CT scan in San Antonio , you may be wondering what to expect. This medical imaging test can be useful in diagnosing a number of bone and soft tissue issues and may also be used to track the effectiveness of a treatment you are already receiving.
Watch this video to learn more about CT scan technology. CTs use the same technology as X-rays, but rather than taking an image from one direction, they create cross-sectional images. During a CT, the staff at the imaging center will position you on a table so that the X-ray beam can effectively reach the part of the body being evaluated, and the table will slide into a tube that lets the beam move in a circle, taking images from a variety of angles. Generally, the entire process takes about 30 minutes.
