What are the known risks and benefits of having a myelogram?

Spine imaging. Myleogram is usually done in conjunction with a ct scan when a MRI may not be indicated such as with a pacemaker, certain metal implanst like aneurysm clips or with very obese patients or even when prior spinal implants make it hard to obtain a clear MRI image. It is an invasive procedure with a contrast material that may cause an allergic reaction, a spinal headache.
Myelogram. Common risks include allergy to the dye, spinal fluid leakage, and infection. Speak to the radiologist as part of informed consent.
