【摘要】：目的探讨CT三维重建图像下腰椎相关影像学参数在老年腰椎不稳诊断中的应用。方法对年龄在60岁以上的120例正常老年人和60例腰椎不稳老年患者的腰椎CT扫描图像进行三维重建,在重建图像上测量L3~S1相邻椎体间的矢状旋转角度Q和相对移位AO/W,比较不同性别正常老年人和腰椎不稳老年患者在矢状旋转角度Q和相对移位AO/W是否存在差异。结果正常老年人和腰椎不稳老年患者的腰椎CT三维重建图像上矢状旋转角度Q和相对移位AO/W指标存在差异集中在L4~L5、L5~S1节段,其中男性和女性在L5~S1:QL4~L5和L5~S1:AO/W这3项参数与腰椎不稳患者的数据比较,差异有统计学意义(P0.05)。结论对于发生在L4~S1这两个节段的老年腰椎不稳患者的诊断应用腰椎CT扫描重建有一定的指导意义。
[Abstract]:Objective to evaluate the application of three-dimensional CT reconstruction in the diagnosis of lumbar instability in the elderly.Methods Third-dimensional CT images of lumbar vertebrae were reconstructed from 120 normal subjects and 60 unstable elderly patients over 60 years of age.Sagittal rotation angle Q (sagittal rotation angle Q) and relative displacement (AOP / W) between adjacent vertebrae of L3~S1 were measured on reconstruction images.Results there were significant differences in sagittal rotation angle Q and relative shift AO/W between normal elderly and unstable elderly patients.The data of male and female patients with L5~S1:QL4~L5 and L5~S1:AO/W were significantly different from those of patients with lumbar spine instability (P 0.05).Conclusion Lumbar CT scan reconstruction is useful for the diagnosis of two segments of L4~S1 in elderly patients with lumbar vertebrae instability.
