Myelography

Myelography is an x-ray of the spinal cord and the spinal canal. An injection of a dye that can be seen on x-ray is made into the space that surrounds the spinal cord and brain. This outlines the spinal cord and makes it visible.

Myelography tests for the following:

• a blockage of the flow of spinal fluid
• tumors or other lesions in the spine or spinal cord
• ruptured disks and
• suspected abnormalities at the base of the brain

A healthcare provider injects the dye at the base of the spine. The person lies on a tilting table under a fluoroscope. This device takes motion x-ray images. The examiners can direct the flow of the dye by tilting the person.

Myelography is not usually done if there is an infection in the spinal cord or surrounding membranes. Complications are rare. They include irritation of the membranes, headache, and infections.

CT scans and magnetic resonance imaging (MRI) have replaced this procedure for many uses.
