Myelography is an imaging examination that involves the injection of contrast material into the space around the spinal cord and nerve roots using a real-time form of X-ray called fluoroscopy.
This type of technology is most commonly used to discover and examine abnormalities relating to the spinal cord, spinal canal, spinal nerve roots, the blood vessels that supply the spinal cord, tumors, infection, and inflammation
Myelography provides a very detailed picture of the spinal cord and spinal column. A radiologist can view the passage of the contrast material within the subarachnoid space as it is flowing. Real time images can be taken of the movement and helps radiologists document abnormalities in the flow. In many cases a myelogram is followed by a CT to better define any potential issues.
This procedure is usually done on an out-patient basis where a radiographic table, X-ray tube and monitor are used. When images are needed, they can be captured on a computer or on film.
Some prescription drugs may interfere with this procedure and must be stopped 2 days prior to the procedure. Consult your specialist if you are taking any medications before undergoing this procedure.
