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.

Before Your Test

  • 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

  • You will change into a hospital gown.

  • X-rays of your spine will be taken.

  • Your lower back will be cleaned, covered with drapes, and injected with a numbing medication.

  • Contrast fluid will be injected into your spinal canal and a small amount of spinal fluid may be withdrawn.

  • Additional x-rays will be taken.

  • If you need a CT test, it will follow the x-rays.
