目的探讨臂丛MRI在产瘫中的诊断价值。方法2006年9月至2011年9月，收治产瘫患儿18例，男12例，女6例；年龄2个月-3岁，平均10．6个月，左侧8例，右侧10例。Tassin Ⅰ型4例，TassinⅡ型6例，Tassin Ⅲ型5例，TassinⅣ型3例。所有患者术前均行臂丛MRI检查，MRI结果与术中结果比较。结果MRI检查结果：18例中有13例发现有假性脑脊膜膨出，10例为多发的似性脑脊膜膨出：脊髓偏移6例。向健侧偏移4例，向患侧偏移2例；未发现异常2例；撕脱神经根增粗2例．结论臂丛MRI可有效地判断产瘫的损伤情况及对手术探查有指导作用。

英文摘要：

Objective To evaluate the value of MR imaging（MRI）in diagosing of obstetrical brachial plexus. Methods Between September 2006 to September 2011 ,eighteen cases （12 males and 6 females） of obstetrical brachial plexus injury had being used for investigation, aging from 2 month to 3 years, average of 10.6 month. Eight left side and 10 right side. Tassin I was 4 cases,Tassin II was 6 cases, Tassin m was 5 cases, Tassin 1V was 4 cases. All cases were performed to MRI test before operating and the result compare with finding during operating. Results Findings of MRI： pseudomeningocele was in 13 of the 18 cases while 10 of the 15 patients had multiple pseudomeningoceles. Displacement of spinal cord was in 6 cases; Normal was 2 cases; thickening of nerve root was in 2 cases. Conclusion MR imaging is an effective tool for demonstrating lesions of the braehial plexus worthy of surgical exploration.
