磁共振成象（MRI）诊断腰椎间盘突出症

Magnetic Resonance Imaging in Diagnosis of Lumbar Intervertebral Disc Hemiation

本文报告了60例术前经磁共振成象(MRI)诊断为腰椎间盘突出症病人的手术探查结果。其诊断正确率为84.2％,假阳性7例,假阴性6例。与CT的正确率相仿。MRI具有对软组织的高分辨率、无侵袭性以及可以做多方向的扫描等优点,在经过技术上的改进后,定将具有更大的临床意义。

The clinical results of preoperative 50 patients diagnosed lumbar intervertebral disc herniation with MRI by surgical exploration were reported. There Were an accuracy of 84. 2% in diagnosis and 6 false -positive results as well as 4 false-negatives. The rcsuKs of study indicated that MRI was equivalent to CT in the diagnosis of herniated disc disease. The aduantageares are non-invasive,high soft tissue contrast and multiplanar imaging capability. Further advances in MRI technology can be expected to enhance its diagnostic value.
