腰椎间盘突出术前神经根增强磁共振表现

MR Appearance of Nerve Root Enhancement in Preoperative Lumbar Disc Herniation

本文分析４３例腰椎间盘突出术前患者增强前后ＭＲ表现：全部病例均有腰间盘突出症状而未行任何脊柱手术，采用１．０Ｔ超导磁共振机，进行Ｔ１加权增强前后扫描。４３例患者中有４０例（８３处）发现异常神经根增强，３０例（６２处）增强发生于间盘突出处，余２１处异常增强与肢体症状相关。神经根鞘内及硬膜内增强可以反映神经根炎性病理生理改变，与间盘突出及临床症状有良好相关性。

This paper was to analyse the MR appearance in lumbar disc herniation(LDH) patients before and after gadolinium administration.43 patients who have not had surgery were examined with 1.0T unit.Total patients with a syndrome of LDH without surgery and T1 weighted adages pre-and post-contrast were studied. 40 of 43 CaSes(83 lesions)shows abnormal nerve root enhancement. Enhancement around herniated disk in 30 patients(62 lesions)and the others with reletive syndroms.Intrathecal and intramural nerve roots enhancement have a possible to detect the pathophysiologic changes of nerve root and have a good correlation with LDH and clinical syndroms.
