| 摘 要： | 目的 探讨弥散加权神经成像术(DW-MRN)对臂丛神经病变诊断的准确性及定量诊断价值. 方法对52例受检者行常规MR序列及重T2脂肪抑制(T2WI/SPIR)和DW-MRN.其中20例臂丛神经病变患者按病理类型分为损伤组、炎症组和肿瘤组. 结果 与T2WI/SPIR比较,DW-MRN臂丛C7神经节的对比噪声比和病灶对比噪声比均较高(t=2.19、3.91,P均<0.05),对臂丛神经病变诊断的灵敏度亦较高(χ~2=4.44,P<0.05).臂丛神经病变的ADC值高于正常神经节和中干(t=4.80、5.69,P均＜0.05);损伤组和肿瘤组的ADC值高于炎症组(F=6.99、5.28,P均＜0.05). 结论 DW-MRN对臂丛神经及其病变有良好的显示能力,ADC值可作为臂丛神经病变的定量诊断的参考指标.
