A myelogram is an invasive diagnostic test that uses x-rays to examine the spinal canal. A special dye is injected into the spinal canal through a hollow needle. An x-ray fluoroscope then records the images formed by the dye. Myelograms can show conditions affecting the spinal cord and nerves within the spinal canal.

How painful is a myelogram?

How does it feel? You will feel a quick sting from a small needle that has medicine to numb the skin on your back. You will also feel some pressure as the long, thin spinal needle is put into your spinal canal. You may feel a quick, sharp pain down your buttock or leg when the needle is moved in your spine.

How long does a myelogram procedure take?

How long does a myelogram take? The time varies depending on the area to be examined. If the procedure is being carried out on your lower back (the most common area), it will take approximately 30 minutes. If the procedure is being carried out on your lower back and neck, it will take approximately 45 minutes.
