Is there anything else I need to know about myelography?
MRI (magnetic resonance imaging) has replaced the need for myelography in many cases. MRIs  use a magnetic field and radio waves to create images of organs and structures inside the body. But myelography can be useful in diagnosing certain spinal tumors and spinal disk problems. It's also used for people who are unable to have an MRI because they have metal or electronic devices in their bodies. These include a pacemaker, surgical screws, and cochlear implants.
