CT Myelograms

CT myelograms use a special form of x-ray called fluoroscopy and an injection of contrast material to evaluate the spinal cord, nerve roots and spinal lining (meninges). When combined with a myelogram, a CT scan provides for excellent nerve detail during an examination of back pain. A myelogram consists of injecting a contrast material into the area around the nerve roots, which in turn lights up the nerve roots. The CT scan follows and shows how the bone is affecting the nerve roots.
