摘要
目的：评价ＭＲＩ对臂丛节后神经损伤的诊断价值。材料和方法：对２５例经手术证实之完整ＭＲＩ资料进行回顾性分析。结果：节后损伤的ＭＲ表现初步分为四型：①正常神经表现型（１２％）；②神经变性型（２４％）；③神经疤痕型（２０％）；④神经消失型（４８％）。其诊断准确性为８９．３％。四种分型代表了不同的损伤程度，有利于临床确定治疗方案。结论：ＭＲＩ是目前臂丛节后神经损伤影像诊断的最佳技术，具有无损伤，操作简单方便，诊断准确性高。
Purpose:To evaluate the role of MRI to post ganglionic injury in brachial plexus.Materals and Methods:MRI data of 25 case with post ganglionic injuries confirmed by operation were analysed,retrospectively.Results:Post ganglionic injury MR findings were classfied four types (normal,degenerative,scar,and absent of nerve),accounting for 12%,24%,20%,48%,respectively.Its diagnostic accuracy is 89.3%.Four types represent different degree of injury,contribute to determine therapeutic plans.Conclusion:MR is an effective imaging technique to post ganglionic injury. It has advantages as follows:non invasive,simple operation,high accuracy,in the same time,preganglionic injury may be observed.
