What is a myelogram?

A myelogram is a special spinal X-ray examination used to help determine the cause of pain, numbness and/or weakness in the back, arms or legs. During the test, a contrast medium (also referred to as contrast material) is injected into the spinal canal under X-ray guidance to provide an outline of the spinal cord and nerve roots. A series of X-ray films are taken.

Please note: The myelogram test may be performed along with other tests such as a Magnetic Resonance Imaging (MRI) Test, Computed Tomography (CT) and regular spinal X-ray films.
