3．0T磁共振对创伤性臂丛神经损伤的诊断价值探讨

目的评价3．0T磁共振（MRI）检查在创伤性臂丛神经损伤诊断中的价值。方法对3l例创伤性臂丛神经损伤患者进行术前MRI各序列检查后，再进行图像后处理，并与手术探查中的发现进行比较；比较术前MRI检查在诊断神经完全性损伤中的作用。结果术前MRI检查对创伤性臂丛神经根损伤的诊断符合率为86．4％；外伤性囊肿的诊断符合率为100％。结论MRI检查可明显提高创伤性臂丛神经损伤的诊断符合率，是一种有前途的辅助诊断、指导治疗臂丛神经损伤的途径。

Study on the significance of 3. OT MRI in diagnosis of traumatic brachial plexus injury.

Objective To evaluate the significance of MRI in diagnosis of traumatic brachial plexus injury. Methods Thirty one cases of traumatic brachial plexus were examined by MRI before operation. The obtained imaging data were processed with post figure treatment. Their re- suits were eompared with the findings in operation. The value of MRI in diagnosis of traumatic brachial plexus injury before operation had been e- valuated. Results The accurate rate of MRI in diagnosis of traumatic braehial plexus nerve root injury before operation was 86.4 %, and the co- incidence rate of traumatie cyst was 100%. Conclusion MRI can raise the accurate rate of diagnosis of traumatic braehial plexus injury, and it is a promising method for auxiliary diagnosis and guiding treatment.
