A myelogram is a test to check problems with your spinal canal, a tunnel-like structure in your spine that holds your spinal cord. A myelogram uses X-ray or computed tomography (CT) to create pictures of your spinal canal.
The exam table may be tilted during the x-ray.

Don't eat the morning of the test, but you can drink water or other clear fluids.
If instructed, stop taking medications before the test.
Arrange for someone to drive you home.
During Your Test

X-rays of your spine will be taken.
Your lower back will be cleaned, covered with drapes, and injected with a numbing medication.
