Myelography can be used to:
– Detect a blockage in the spinal canal that may be caused by a tumor or by a spinal disc that has ruptured (herniated).
– Detect inflammation of the membrane (arachnoid membrane) that covers the brain and spinal cord.
– Detect abnormalities in the blood supply to the spinal cord.
– Detect problems of the spinal cord and the nerves that branch off from the spinal cord.
