摘　　要：目的比较负重位磁共振成像(magnetic resonance imaging,MRI)与平卧位MRI评估腰椎前凸的价值。方法回顾分析24例腰痛患者分别行负重位和平卧位MRI检查,测量腰椎Cobb’s角、四线Cobb’s角、腰骶角、腰椎高度、腰椎前凸距离、腰椎前凸角度等参数,配对样本t检验或Wilcoxon符号秩和检验比较差异。结果24例中,腰椎负重位MRI与腰椎平卧位MRI的腰椎Cobb’s角[(31.05±13.65)°vs.(27.95±11.81)°]、腰椎前凸距离[(2.32±0.75)cm vs.(1.96±0.75)cm]、腰椎前凸角度[(34.58±11.90)°vs.(30.51±11.14)°]、腰椎高度[(16.66±1.34)cm vs.(16.80±1.08)cm]之间差异有统计学意义(腰椎Cobb’s角,t=2.647,P=0.014;腰椎前凸距离,t=8.141,P<0.001;腰椎前凸角度,t=4.178,P<0.001,腰椎高度Z=2.015,P=0.044);四线Cobb’s角、腰骶角之间差异无统计学意义(四线Cobb’s角,t=0.656,P=0.519;腰骶角,t=-1.881,P=0.073)。结论腰椎负重位MRI对腰椎前凸的评估具有重要的参考价值。Objective To compare the differences of lumbar lordosis assessed on weight-bearing magnetic resonance imaging(MRI)and recumbent MRI images.Methods Both weight-bearing MRI and recumbent MRI were employed for 24 subjects.The MRI images were retrospectively reviewed.Six parameters including Cobb’s angle,four-line Cobb’s angle,sacral angle,lumbar height,lumbar lordosis distance and lumbar lordosis angle were measured.The differences were compared by paired samplest test or Wilcoxon signed-rank test.Results There were signifcant differences for 24 subjects in lumbar Cobb’s angle[(31.05±13.65)°vs.(27.95±11.81)°,t=2.647,P=0.014],lumbar lordosis distance[(2.32±0.75)cm vs.(1.96±0.75)cm,t=8.141,P<0.001],lumbar lordosis angle[(34.58±11.90)°vs.(30.51±11.14)°,t=4.178,P<0.001],and lumbar height(Z=2.015,P=0.044)between weight-bearing MRI and recumbent MRI.No difference in four-line Cobb’s angle(t=0.656,P=0.519)and sacral angle(t=-1.881,P=0.073)was demonstrated.Conclusions The importance of weight-bearing imaging in evaluating the lumbar lordosis is validated.
