【摘要】：目的评估全脊柱数字化成像技术(DR)与MR成像质量,分析全脊柱站立位DR及仰卧位MR成像的测量的矢状面参数的差异及相关性。方法搜集2010年11月~2016年3月到我院就诊并诊断为退行性脊柱病的61名患者资料,年龄49.9±17.6岁,均行全脊柱站立位DR与仰卧位MR检查,分析全脊柱拼接的图像质量,在全脊柱DR侧位片、全脊柱MR正中矢状位图像测量颈椎前凸角(CL)、胸椎后凸角(TK)、腰椎前凸角(LL)、骶椎倾斜角(SS)、脊柱矢状位垂直轴(SVA)等参数,并利用配对T检验对比DR与MR测量值,并进行Pearson相关性分析。结果全脊柱DR与MR图像拼接质量优良率为100%,全脊柱DR及MR成像上测量CL、TK、LL、SS、SVA值分别为28.37±10.91o、29.98±8.96o、45.61±12.46o、34.38±9.05o、17.20±26.39 mm,及24.34±9.01o、21.22±8.13o、41.45±12.17o、37.45±8.19o、36.51±12.44 mm,DR与MR测量CL、TK、LL、SS、SVA值存在统计学差异(P值分别为0.000、0.000、0.000、0.001、0.007),相关系数r分别为0.69、0.68、0.72、0.51(P值分别为0.000、0.000、0.000、0.000、0.034)。结论站立位DR与仰卧位MR全脊柱成像图像质量良好,仰卧位MR图像测量的CL,TK,LL,SS,SVA等脊柱矢状面平衡参数与站立位DR相关,但存在明显区别,并不能代替站立位DR检查,须联合检查才能全面评估退行性脊柱病改变。
[Abstract]:Objective to evaluate the digital imaging of the whole spine (DRR) and the quality of Mr imaging, and to analyze the difference and correlation of the sagittal parameters measured in the standing position of the whole spine and the supine position.Methods from November 2010 to March 2016, 61 patients, aged 49.9 卤17.6 years, who were admitted to our hospital and diagnosed as degenerative spondylosis, were examined in the whole spine standing position Dr and supine position, and the image quality of the whole spine splicing was analyzed.Mr median sagittal images of the whole spine were used to measure the parameters of CLV, TKT, LLN, SSS and SVA in the lateral position of the whole spine, and to compare Dr with Mr measurements by paired T test.Pearson correlation analysis was carried out.缁撴灉鍏ㄨ剨鏌盌R涓嶮R鍥惧儚鎷兼帴璐ㄩ噺浼樿壇鐜囦负100%,鍏ㄨ剨鏌盌R鍙奙R鎴愬儚涓婃祴閲廋L,TK,LL,SS,SVA鍊煎垎鍒�涓�28.37卤10.91o,29.98卤8.96o,45.61卤12.46o,34.38卤9.05o,17.20卤26.39 mm,鍙，
