| 摘 要： | 目的探讨磁共振成像（MRI）与皮节体感诱发电位（DSEP）分别及联合应用诊断腰椎间盘突出症的价值,并比较各自的优缺点。方法分析65例经手术确诊的腰椎间盘突出症患者术前MRI和DSEP的检查结果,并进行比较。结果 术前MRI检测的阳性率达96.9%（63/65）,DSEP检测的阳性率达90.8%（59/65）,两者合用检测的阳性率达100%（65/65）;MRI诊断正确而DSEP漏诊者6例,DSEP诊断正确而MRI漏诊者2例。结论 MRI与DSEP检查各有独特之处,前者既可判断神经根功能又可初步定位,但阳性率略低于MRI,后者能直接显示椎间盘的形态改变和精确定位,但对于部分椎间盘突出类型如椎间孔型容易漏诊,两者应相互补充,为腰椎间盘突出症的诊断和治疗提供更全面的信息。

| Abstract: | Objective To study comparatively the value of the MRI and dermatomal somatosensory evoked potential(DSEP) in evaluation of lumbosacral disc herniation(LDH).Methods MRI and L5 and S1 DSEP were recorded from 65 patients with radiculopathy caused by LDH pre-operation.The diagnosis was finally confirmed by surgery.Results In comparison with surgical findings.the positive rates of MRI and DSEP were 96.9%(63/65) and 90.8%(59/65) respectively.The positive rate was 100%(65/65) when these two examinations methods we... |
