What Is A Myelogram?

A myelogram is an x-ray test used to image the space that surrounds your spinal cord. It is helpful in diagnosing problems affecting the spinal cord and nerves.

The Procedure:

In x-ray, the technologist will ask you to lie on your stomach on the table. Preliminary x-rays of your spine may be taken at this time.

The Radiologist will then clean and numb an area on your back, and a needle will be placed into the spinal canal. The dye will be injected into the spinal column and the needle will then be removed.

The Radiologist will begin filming your spine. You will be asked to turn from side-to-side to help distribute the dye throughout the spinal canal. The x-ray table may also be tilted to help distribute the dye.

Following the myelogram, you will be placed on the cart lying on your back and with your head elevated. This position will keep the x-ray contrast down in the spinal column.

You will be taken to the CT department and asked to lie on a table and images of your spine will be obtained.
