Magnetic Resonance Imaging of Cervical Spinal Stenosis
We have had the opportunity to examine the cervical spines of 121 patients utilizing a 0.6 Tesla magnetic resonance (MR) imaging unit manufactured by Technicare Corporation, Solon, Ohio. Thirty-one patients demonstrated degenerative changes in the cervical spine without cord compression, while 19 patients with myelopathy, demonstrated evidence of cervical spinal stenosis. Fourteen of the latter underwent myelography, 13 of which confirmed the evidence of narrowing of the spinal canal causing resultant compressive changes in the spinal cord. One false positive MR study was encountered. Seventeen of seventeen patients who had plain radiographs demonstrated abnormalities, however, in only 6 cases could one make the definitive diagnosis of cervical spinal stenosis from the plain films alone.
