Myelography is a diagnostic procedure that provides detailed images of the spinal canal, including the spinal cord, nerve roots, and other tissues.
During myelography, a contrast agent is injected into the spinal column and X-rays or computed tomography (CT) scans are taken. The contrast agent outlines the spinal cord and can help show areas where the spine is narrowed or compressed.
General anesthesia or a mild sedative may be used to make the procedure more comfortable.
Myelography can be used to diagnose various problems with the spine, including:
- Spinal tumors
- Herniated discs (discs that bulge and compress nerves and/or the spinal cord)
- Degenerative disc disease
- Blood vessel abnormalities (vascular malformations)
- Spinal stenosis (narrowing of the spine due to degeneration, disease, or trauma)
- Injury of spinal nerve roots
- Infection or inflammation of tissues around the spinal cord
You may be a good candidate for myelography if you have symptoms of a spinal disorder. Your doctor may recommend other diagnostic tests if you have had allergic reactions to contrast agents in the past or if you are pregnant.
