A myelogram is an x-ray test to check your spinal cord and nerves. A small
amount of radioactive dye is given for this test. The dye leaves your body
after a few days.

If you have any allergies to medicines, foods or other things, tell the
staff before the test.

If you are pregnant, or think you might be, tell the staff before the test.

An adult family member or friend needs to come with you to take you home
after the test. It is not safe for you to drive or leave alone.
