Myelography is an examination of the spinal cord and the space around it. Myelograms render images that show distortions of the spinal cord, the spinal canal, and the spinal nerve roots. Myelograms are performed for the following reasons:
- To detect spinal lesions or other abnormalities.
- Ruptured or herniated disks.
- Bone spurs causing back pain due to pressure on nerves.
- Tumors in the spine or around the tissue.
- Infection, inflammation, abnormalities of blood vessels that supply the spinal cord, and other traumatic injuries.
