摘要
目的探讨MRI对于腰椎间盘突出病理分型的诊断价值。方法比较242例腰椎间盘突出症病例的MRI检查结果与手术所见。结果手术证实242名患者中包含型椎间盘突出129例,非包含型113例。轴位MRI区分包含型与非包含型椎间盘突出的敏感性、特异性和准确性分别为77.9%、72.1%和74.8%,矢状位为80.5%、76.0%和78.1%。结论根据MRI检查结果区分包含型与非包含型椎间盘突出并不可靠。
Objective To determine the value of magnetic resonance imaging(MRI) in subclassification of lumbar disk herniations. Methods A total of 242 patients with lumbar disk herniation were prospectively evaluated for their MRI data, and the findings at operation were compared to assess the accuracy of the MRI classification. Results Of these patients, 129 had a contained herniated disk, while 113 sustained a noncontained lesion. There were 77 9% sensitivity, 72 1% specificity and 74 8% accuracy for axial MRI, and 80 5% sensitivity, 76 0% specificity and 78 1% accuracy for sagittal MRI, in differentiating noncontained from contained disk herniations. Conclusion For differentiating noncontained from contained disk herniations, MRI is far from reliable.
