NMR is rapidly becoming the examination of choice for the diagnosis of syringomyelia and Chiari malformation. NMR is also useful for the examination of intramedullary tumors and may replace CT and myelography for the examination of some, if not all, of these lesions. The role of NMR in the diagnosis of other tumors related to the spinal cord is being evaluated.

Since NMR cannot currently visualize herniated discs, the neural foramina and the lateral recesses as well as CT or myelography, it cannot currently replace these studies for the evaluation of sciatica. It must be determined if future improvements in NMR will allow it to be used as a replacement for CT and myelography in the detection of a herniated nucleus pulposus and in the evaluation of degenerative disease. NMR should also prove useful in the evaluation of spinal trauma and disc space infection.
