摘　　要：目的观察正常神经根、术前椎间盘突出神经根及椎间盘突出术后神经根FA值及ADC值,探讨腰神经根受压损伤的定量评估方法。方法 选择健康查体志愿者50例作为对照组,39例椎间盘突出患者作为实验组。测量正常腰神经根及受压腰神经根的FA值及ADC值。比较:(1)对照组与实验组FA值及ADC值。(2)对照组内不同影像表现的FA值及ADC值。(3)手术前后FA值及ADC值。(4)对照组与实验组术后的FA值及ADC值。所测数据使用SPSS17.0软件进行数据分析,若P<0.05为差别有统计学意义。结果(1)对照组与实验组:FA值比较,z值-9.246,P值0.000。ADC值比较,z值-6.762,P值0.000。P值均<0.05,认为2组数据有明显差别。(2)对照组内不同影像表现的FA值及ADC值:FA值比较,t值1.459,P值0.151;ADC值比较,t值0.075,P值0.940。P值>0.05,认为2组数据没有差别。(3)手术前后FA值与ADC值:FA值比较,t值-12.083,P值0.000;ADC值比较,t值7.870,P值0.000。认为P值<0.05,2组数据有明显差别.(4)对照组与实验组术后的FA值及ADC值:FA值比较,t值1.859,P值0.066;ADC值比较,t值-1.137,P值0.259。P值>0.05,认为2组数据没有差别。结论 MR DTI测量椎间盘突出受压神经根FA值与ADC值,可以用于定量评估腰神经受压损伤。Objective To observe the FA value and ADC value of normal lumbar nerves,lumbar nerves compressed by disc herniation before and after surgery and to explore the quantitative evaluation method of lumbar nerve root compression injury.Methods Fifty healthy volunteers were selected as the control group and thirty-nine patients with disc herniation as the experimental group.FA value and ADC value of normal lumbar nerve root and compressed lumbar nerve root were measured in each group.The following parameters were compared:(1)FA value and ADC values of the control group and the experimental group;(2)FA and ADC values of different imaging findings in the control group;(3) FA and ADC values before and after surgery;(4)FA and ADC values of the control group and surgical group.The measured data were analyzed using SPSS17.0 software.Statistically significant was considered for P values less than 0.05.Results (1)Control group and experimental group:the z value was -9.246 and P value was 0.000 for comparison of FA value.In comparison of ADG,the z value was -6.762 and P value was 0.000.It was considered that the two groups of data had significant differences.(2)FA value and ADC value of different imaging manifestations in the control group:the t value and P value were 1.459 and 0.151 ,respectively,in the comparison of FA value.In the comparison of ADC value,the t value was 0.075 and P value was 0.940.There was no difference between the two groups.(3)FA value and ADC value before and after surgery:comparison of the FA value showed that the t value was -12.083 and the P value was 0.000;the t value was 7.870 and P value was 0.000 in the comparison of ADC value.There was a significant difference.(4)FA value and ADC value of the control group and surgery group:comparison of the FA value showed that the t value was 1.859 and the P value was 0.066;the t value was -1.137 and P value was 0.259 in the comparison of ADC value.There was no difference between the two groups. Conclusion The FA and ADC values of compressed nerve roots measure
