2、面积(CAD)和硬膜外间隙(LAC),对两组患者的测量结果及腰椎管狭窄症组测量结果与JOA评分的相关性进行统计学分析,筛选出最能客观反映腰椎管狭窄程度的CT测量指标,作为腰椎管狭窄症的诊断标准。结果腰椎管狭窄组L4/5及L5/S1两节段的APDC、CAC、ICA、CAD和LAC均显著小于正常组(P<0.01)。APDC、CAC、ICA、CAD和LAC对L4/5、L5/S1椎管狭窄的诊断符合率分别为73.19%、88.41%、92.02%、78.98%、96.37%和73.75%、87.23%、91.49%、78.72%、95.74%;且硬膜囊面积/
3、椎管面积与患者JOA评分都有显著相关性。结论CT图像测量在腰椎管狭窄症诊断中有助于腰椎管狭窄症的诊断,具有重要的应用价值。关键词:腰椎;测量;CT;形态学中图分类号:R814.42文献标志码:A文章编号:1674-0424(2013)05-0054-03TheApplicationofCTImageMeasurementintheDiagnosisofLumbarSpinalStenosis1,2231YUZhiying,LIHongxiu,ZHANGLi,ZENGXiangyi(1.LiaoningMedicalUniversity,Jinzho
