How To Prepare
Your doctor will tell you if you need to change how much you eat and drink before the myelogram. You may be asked to increase the amount of water you drink before the test. Follow the instructions exactly about eating and drinking, or your test may be canceled.
Before a myelogram, tell your doctor if you:
Arrange to have someone take you home and stay with you after the test.
Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).
How It Is Done
The test is done by a doctor in a radiology center or in the radiology department of a hospital.
You will need to take off jewelry that might be in the way of the X-ray picture. You may need to take off all or most of your clothes above the waist (you may be allowed to keep on your underwear if it does not get in the way of the test). You will be given a gown to wear during the test.
During the test
You will have a lumbar puncture to put the dye into your spinal canal. You will lie on your stomach or side on an X-ray table. The doctor cleans an area on your lower back. A numbing medicine is put into your skin.
After the area is numb, a thin needle is put into the spinal canal and a stream of X-rays (fluoroscopy) is used to help the doctor place the needle in the right area. A sample of spinal canal fluid may be taken before the dye is put in the canal.
