摘要
目的分析CT图像面积测量在腰椎管狭窄症诊断中的应用价值。方法选取收治的70例腰椎管狭窄症为观察组,选取同期腰椎正常健康者70例为对照组,采用CT图像分析系统测量椎间隙(L4/5、L5/S1)椎管矢状径(APDC)、椎管内切圆面积(ICA)、椎管面积(CAC)、硬膜囊面积(CAD)及硬膜外间隙(LAC),分析相关测量指标与腰椎功能JOA评分的相关性。结果观察组各节段APDC、ICA、CAC、CAD及LAC等测量值均低于对照组(P<0.05);经Pearson相关性分析,CAC(r=0.259,P<0.05)、CAD(r=0.247,P<0.05)与腰椎功能呈正相关。结论 CT图像面积测量可作为腰椎管狭窄诊断的有效手段。
