Myelography is an imaging procedure which visualizes the fluid (cerebrospinal) surrounding the spinal nerves and intervertebral disks. A myelogram is often used to specifically to visualize the effect of a herniated disk on the spinal nerves.
A myelogram is performed by first injecting a local anaesthetic into the back. Under x-ray (fluoroscopic) guidance, a small needle is inserted into the spinal canal, the tip of the needle located within the space that contains the cerebrospinal fluid. Contrast dye is then injected making the spinal sac and its contents visible on fluoroscopy and x-ray film. The needle is removed and x-rays taken
