Imaging strategies for MR of the spine.

Magnetic resonance (MR) imaging has rapidly evolved as a primary modality for evaluating the spine. Following routine radiographs, MR is currently the preferred examination in evaluating patients presenting with myelopathy, suspected congenital abnormalities, discitis/osteomyelitis, and myeloradiculopathy. It is becoming the examination of choice in evaluating patients with radiculopathy as well when fast-scan techniques are available. MR of the spine will prove increasingly important as the technology advances. It is likely that MR will replace myelography entirely for many indications.
