Things to consider when receiving a myelogram to diagnose neck or back pain
Using a myelogram to diagnose neck and back pain
A myelogram is an imaging test that uses a contrast dye injection and X-rays to develop images of the spinal canal. The dye allows physicians to see the fluid-filled spinal nerve rootlet cuffs. The bones themselves are seen on the X-ray portion of the myelogram
Myelograms are good alternative tests for people who cannot undergo MRIs due to metal implants that would be affected by the MRI’s powerful magnetic field. The contrast material used in myelograms makes them a good tool for detecting problems such as a narrowing of the spinal canal (spinal stenosis), herniated discs, sciatica, pinched nerves and other causes of neck or back pain.
How is a myelogram performed?
Myelograms are usually performed in outpatient radiology centers or hospital radiology departments. Radiologists, who specialize in imaging tests, perform the procedure with their teams. A lumbar (lower back) puncture to inject the contrast material into the fluid surrounding the spinal cord is part of the procedure.
After you have removed all of your jewelry and clothes that might interfere with the test, you will be asked to change into a gown and lie on your stomach or side on the X-ray table. The radiologist will numb the skin above your lumbar spine with a local anesthetic and then inject the contrast dye. During this process, X-rays are used to help the radiologist position the needle and make sure the dye is injected in the right spot. Once the dye is absorbed, X-ray pictures are taken. You may be asked to lie still or to move to different positions. An MRI may also be taken while the dye is in your system.
Before getting a myelogram, it is important to note a few key considerations. You may be at risk of:
- Experiencing severe headaches, nausea or vomiting. This typically occurs after the procedure, and the risk is higher in females, particularly young females.
- Having a seizure. Seizures are rare and only occur if the dye enters your brain. This is why you are advised to avoid lowering your head below your center of gravity until after the dye has had a chance to clear your system.
- Experiencing an allergic reaction to the dye. Some people may have an allergic reaction to the dye, in which case medications are given to relieve the allergy.
- An infection to the lumbar puncture site and meningitis. There is also a risk that the puncture to the spinal sac may not heal. A procedure to repair the puncture may be required if this happens.
- A spinal hematoma. This requires surgical drainage, particularly for those taking blood thinning medications.
Always make sure you are completely comfortable with any diagnostic procedure that your physician recommends. Ask questions and do your own research on the subject so that you will be prepared and know what to expect.
After your myelogram
If your myelogram results indicate that you may have a spine condition, or you are experiencing neck and back pain that led you to receive a myelogram in the first place, it may be best to meet with your physician. He or she can help you explore your treatments options, including both surgical and nonsurgical options.
