Myelogram
A myelogram is a test to check problems with your spinal canal. The canal is a tunnel-like structure in your spine that holds your spinal cord. A myelogram often uses a real-time form of X-ray (fluoroscopy) or CT to take pictures of your spinal canal.
A myelogram is a test to check problems with your spinal canal. This includes the spinal cord, nerve roots, and spinal lining. The canal is a tunnel-like structure in your spine that surrounds your spinal cord. A myelogram uses a dye injected into the spinal canal with the guidance of imaging. The imaging is typically done by a real-time form of X-ray (called fluoroscopy). Pictures are then taken of your spinal canal.
How do I get ready for a myelogram?
Don’t eat the morning of the test. But you can drink water or other clear fluids.
If told to, stop taking medicines before the test.
Arrange for someone to drive you home.
What to tell the person doing your study
Tell the healthcare provider if you:
Are pregnant or think you may be pregnant
Have any bleeding problems
Take blood thinners (anticoagulants) or other medicines. These include aspirin, certain antipsychotic medicines, and antidepressants. You may be told to stop taking these 1 or more days before your test.
Have had back surgery or low back pain
Have any allergies
What happens during a myelogram?
You will change into a hospital gown.
Your lower back will be cleaned, covered with drapes, and injected with a numbing medicine.
Your healthcare provider will use X-rays (fluoroscopy) to guide a thin needle into your spinal canal space.
The healthcare provider may take out a small amount of cerebrospinal fluid (CSF). The provider will inject dye (contrast fluid) into your spinal canal.
The table will be tilted in various directions to help move the contrast dye to different areas of your spinal canal.
More X-rays will be taken.
If you need a CT test, it will follow the X-rays.
What happens after a myelogram?
Take it easy for the rest of the day, as advised.
Don't do any physical activity or bending for 1 to 2 days after the procedure, or as directed by your healthcare provider.
Lie down with your head raised if you get a headache, or if directed to do so.
Drink plenty of water.
Your healthcare provider will discuss the test results with you at a follow-up appointment.
What are the risks of a myelogram?
Small risks of pain, bleeding or infection at the injection site or in or around the spinal canal
Headache
CSF leak that may need a blood patch or other treatments
Injury to a nerve or the spinal cord at the injection site
X-ray radiation exposure (generally believed to be low risk and safe)
When should I call my healthcare provider?
Call your healthcare provider right away if any of the following occur:
A headache that lasts 2 days or more
Fever of 100.4 °F (38°C) or above, or as directed by your healthcare provider
Chills
Severe upset stomach or vomiting
Trouble urinating or having a bowel movement
Lasting pain in your back, or tingling in your groin or legs
Or anything else your provider told you to report based on your health condition
