我们研究了35例成人外伤性臂丛神经损伤的MRI诊断准确性，并与术中所见进行了比较。检测牙根撕脱的总体敏感性为39%，特异性为75%。MRI对下牙根撕脱的诊断更有价值。在躯干和分区水平损伤，敏感性为87%，但特异性仅为26%。它不能区分节后损伤的类型和程度。手术诊断假性脑膜膨出与撕脱伤的符合率为96%（27/28）。假性脑膜膨出与根性撕脱相关。它的存在需要早期转诊和手术探查。
We studied the diagnostic accuracy of MRI in 35 adult patients with traumatic brachial plexus injury in comparison with intra operative findings. The overall sensitivity to detect root avulsions was 39% and specificity was 75%. MRI was more useful in the diagnosis of lower root avulsions. At trunk and division level injuries, the sensitivity was 87% but specificity was only 26%. It was not able to differentiate the type and extent of postganglionic injuries. The accuracy of pseudomeningocele as avulsion on surgical finding was 96% (27/28). Pseudomeningocele correlates well with root avulsions. Its presence warrants early referral and surgical exploration.
