摘要目的 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,TassinⅢ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例为多发的假性脑脊膜膨出;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.

abstractsObjective 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 eases, Tassin Ⅲwas 5 eases, Tassin Ⅳ 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 18cases 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 brachial plexus worthy of surgical exploration.
