颈髓磁共振T2高信号改变对脊髓型颈椎病预后判断的临床意义

目的探讨颈髓MRIT2高信号的改变能否预测脊髓型颈椎病（CSM）手术治疗的效果。方法53例CSM患者，合并后纵韧带骨化症（OP虬）18例，病程2个月～11年，平均25．7个月。根据日本矫形外科学会（JOA）制定的脊髓功能评分标准对其手术前后疗效与MRI进行对比，观察脊髓内r12高信号的不同与临床预后之间的关系。结果所有患者均随访3个月～1年，平均6月。术前病程长、MRIT2加权像长节段高信号患者往往病情重，预后较差（P〈0．05）；多数病程短、单节段高信号患者恢复良好。结论颈髓MRIT2高信号对CSM预后判断有重要意义。

The Clinical Prognostic Value of Cervial Intramedullary High Instensity Lesion on T2 - weighted MR Images in Cervical Spondylotic Myelopathy

Objective To investigate the clinical significance and effect estimate of intramedullary high intensity lesion on T2 weighted MRI in the cervical spondylotic myelopathy. Methods This study is comprised of 53 patients of cervical spondylotic myelopathy,with an average course of 25.7 months(range,2 months to 11 years).18 patients were combined with OPLL.According to the Japanese Orthopedic Association(JOA) score,the pre-and postoperative neurological statuses and MRI images were compared to observe the relati...
