Myelography is a type of x-ray of the spinal cord and the spinal canal. A dye that can be seen with x-rays is injected into the space that surrounds the spinal cord and brain. This outlines the spinal cord and makes it visible.
Myelography tests for the following:
CT scans and magnetic resonance imaging (MRI) have replaced this procedure for many uses.
You will be instructed not to eat or drink for 8 hours before the test. Sometimes your healthcare provider will have you take a laxative or an enema so that your bowels are also empty. Follow your provider's instructions.
Your provider typically injects the dye at the base of the spine. You lie on a tilting table under a fluoroscope. This device takes motion x-ray images. Tilting of the table allows direction of the flow of the dye in your body.
After the test, you will be instructed to keep your head elevated and to avoid bending over. Someone will need to drive you home.
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.
