What is a myelogram?
A myelogram is a test used to evaluate a patient's spine. A myelogram uses a contrast agent, X-rays, and a CAT scan to produce detailed images.
A doctor may order a myelogram for chronic back pain. A computed tomography (CT) scan or magnetic resonance imaging (MRI) scan may be performed first to determine the cause of the pain, but if these tests are not enough to provide a definitive diagnosis, a myelogram may be needed to provide more information.
A myelogram involves injecting a contrast agent into the spinal cord and surrounding areas, such as nerves and soft tissues, to provide a clearer picture.
A myelogram can diagnose the following conditions:
- A herniated disc;
- Arthritis in the joints of the spine;
- Spinal stenosis;
- Spinal tumor;
- Osteophyte.
A myelogram is also ordered in clinical situations where surgery has been performed and the patient is experiencing weakness or pain after the procedure.
