Computerized tomography (CT or CAT scans) combines x-ray science with computer technology to produce more focused and informative images than traditional x-rays. CT scans produce clear pictures of bone, soft tissue, organs, intervertebral discs and the spinal cord. The images can be reproduced in black/gray/white tones or color. To enhance the image, a contrast medium (dye) can be injected into the patient during the test. At our practice we use CT scans to diagnose various spinal disorders including herniated or bulging discs, fractures, infection, tumor, nerve impingement, and degenerative disc disease.
