A CT scan is a noninvasive diagnostic test that uses x-rays and a computer to create images of the body. It allows your doctor to view your spine or brain in slices, as if it were sliced layer-by-layer and a picture taken of each slice. This test can help diagnose tumors, hemorrhages, head injuries, and bone abnormalities.
Discogram is an invasive diagnostic test that uses x-rays to examine the intervertebral discs of your spine. A special dye is injected into the injured disc or series of discs. The dye makes the disc visible on a fluoroscope x-ray. Discograms are used to locate precisely which discs are damaged and causing pain.
