The relationship between pre- and postoperative magnetic resonance (MR) images was investigated with special reference to increased signal intensity in the spinal cord on the T<jats:sub>2<\/jats:sub>-weighted images and the relevance of this finding to clinical conditions. Preoperatively, there were areas of increased signal intensity in 12 patients whereas there were no areas of increased signal intensity in the other 17. The lesions were not clearly demonstrated on T<jats:sub>1<\/jats:sub>-weighted images. The pre- and postoperative clinical condition of the patients whose preoperative MR images showed areas of increased signal intensity in the spinal cord on T<jats:sub>2<\/jats:sub>-weighted images was worse than that of the patients who did not have areas of increased signal intensity. Of the 12 patients with regions of increased signal intensity preoperatively, five showed decreased signal intensity postoperatively compared to the preoperative levels and seven had no change. The postoperative recovery of the five patients who showed decreased signal intensity postoperatively was better than that of the seven patients who exhibited no change. The areas of increased MR signal in the spinal cord might be due to edema, cord gliosis, demyelination, or microcavities.<\/jats:p>","DOI":"10.3171\/jns.1991.74.6.0887","type":"journal-article","created":{"date-parts":[[2009,5,19]],"date-time":"2009-05-19T16:22:10Z","timestamp":1242750130000},"page":"887-892","source":"Crossref","is-referenced-by-count":155,"title":["Increased MR signal intensity due to cervical myelopathy"],"prefix":"10.3171","volume":"74","author":[{"given":"Yasutaka","family":"Matsuda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazumi","family":"Miyazaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Tada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Yasuda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomitaka","family":"Nakayama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Murakami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michimasa","family":"Matsuo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Comput Assist Tomogr","doi-asserted-by":"publisher","first-page":"847","DOI":"10.1097\/00004728-198509000-00001","article-title":"Enhancement of cervical intraspinal tumors in MR imaging with intravenous gadolinium-DTPA.","volume":"9","author":"Bydder","year":"1985"},{"key":"b2","series-title":"Cardiovasc Intervent Radiol","doi-asserted-by":"publisher","first-page":"283","DOI":"10.1007\/BF02552364","article-title":"High field, thin section nuclear magnetic resonance imaging of the cervical spine.","volume":"8","author":"Dee","year":"1986"},{"key":"b3","series-title":"Radiology","doi-asserted-by":"publisher","first-page":"387","DOI":"10.1148\/radiology.161.2.3763906","article-title":"Hemorrhage and edema in acute spinal cord compression: demonstration by MR imaging.","volume":"161","author":"Hackney","year":"1986"},{"key":"b4","series-title":"Acta Neuropathol","doi-asserted-by":"publisher","first-page":"123","DOI":"10.1007\/BF00697194","article-title":"Pathology of spinal cord lesions caused by ossification of the posterior longitudinal ligament.","volume":"63","author":"Hashizume","year":"1984"},{"key":"b5","series-title":"Neuroradiology","doi-asserted-by":"publisher","first-page":"545","DOI":"10.1007\/BF00339698","article-title":"Further aspects of MR-signal enhancements in stenosis of the cervical spinal canal.
