摘　　要：目的探讨腰椎间盘轴位CT影像中对腰椎侧弯的提示性征象。资料与方法运用常规阅片、轮廓勾画法对49例脊柱侧弯(均累及腰椎)及无侧弯患者245个L1～S1椎间盘CT轴位影像进行评价。两组间比较采用χ2检验。结果侧弯组腰椎间盘轴位CT影像可见多个椎体双侧附件不对称、骨性终板"半月征"、"侧移征"、椎体断面旋转、相邻椎体"侧缘错位征"、"后缘相交成角征"、不对称性退变、椎间盘不对称膨出、"假性膨出征"多见、双侧腰大肌不对称,分别为49、49、49、44、49、39、29、36(51个)、49(139个)、18例,无侧弯组分别为10、9、1、1、3、0、8、13(23个)、18(68个)、0例,两组比较,差异均有显著统计学意义(P值均<0.01)。结论侧弯腰椎椎间盘轴位CT具有一定影像特点,准确认识,对疑似侧弯者,可提示诊断。Objective To study the indicative signs on disc axial CT images in diagnosis of lumbar scoliosis.Materials and Methods 245 L1 ～ S1 disc axial CT images of 49 patients with or without lumbar scoliosis were evaluated by conventional and outline sketch method.χ2 test was used as the statistical method.Results In lumbar scoliosis group,the following signs on CT images were more common：asymmetric vertebral accessories（n = 49）,bony end-plate ＂half moon sign＂（n = 49）,＂sway sign＂（n = 49）,vertebral rotation section（n = 44）,＂side edge dislocation sign＂between adjacent vertebral body（n = 49）,＂posterior edge of vertebral body cross sign＂（n = 39）,asymmetric degeneration（n = 29）,disc asymmetric bulging（n = 36,51 case）,pseudo-bulging signs（n = 49,139 case）,asymmetric psoas major（n = 18）.In nonlumbar scoliosis group,however,the corresponding signs were significantly less than in lumbar scoliosis group（P 0.01）.Conclusion Lumbar scoliosis can demonstrate by certain characteristic signs on disc axial CT images.These sings contribute to the diagnosis of lumbar scoliosis.
