摘　　要：目的对腰椎终板Modic改变相邻结构的磁共振(MR)脂肪定量进行比较。方法(1)以终板Modic改变发生率最高的L_(5)~S_(1)椎间盘为研究对象,收集腰椎终板Modic改变患者55名,在常规腰椎MRI扫描后加用脂肪分析计算技术(FACT)序列扫描;(2)测量各终板Modic改变上椎体脂肪分数面积加权值(SFFaw)、下椎体脂肪比面积加权值(IFFaw)、邻近双侧腰大肌和多裂肌的脂肪分数面积加权值(FFaw)、髓核T2信号强度(SI)值及Pfirrmann评分;(3)比较L_(5)~S_(1)各终板Modic改变的SFFaw、IFFaw、腰大肌和多裂肌的FFaw及Pfirrmann评分的差异;(4)分析L_(5)~S_(1)椎间盘Modic1型、2型的SFFaw、IFFaw、腰大肌和多裂肌的FFaw与髓核T2信号SI值的相关性;(5)分析L_(5)~S_(1)椎间盘所有终板Modic改变的SFFaw、IFFaw、腰大肌FFaw、多裂肌FFaw与Pfirrmann评分值的相关性。结果(1)L_(5)~S_(1)椎间盘Modic 1、Modic 2、Modic 3的SFFaw、IFFaw、多裂肌FFaw、腰大肌FFaw、髓核T2信号SI值、Pfirrmann评分值的差异有统计学意义(P<0.05)。(2)L_(5)~S_(1)椎间盘Modic 1、Modic 2的SFFaw、IFFaw、多裂肌FFaw、腰大肌FFaw值与髓核T2信号SI值呈Spearman负相关,P<0.05,有统计学意义;(3)L_(5)~S_(1)椎间盘所有终板Modic改变的SFFaw、IFFaw、腰大肌FFaw、多裂肌FFaw与椎间盘的Pfirrmann评分呈正相关,P<0.05,有统计学意义。结论L_(5)~S_(1)椎间盘各终板Modic改变相邻结构的脂肪含量比较有差异,并与椎间盘的退变存在一定的相关性。Objective To compare fat quantification in adjacent structures of lumbar endplate Modic change.Methods The L_(5)-S_(1)intervertebral disc with the highest incidence of Modic was taken as the research object,55 patients with endplate Modic change were collected,and the FACT sequence scan was added after the routine lumbar MRI scan;The area-weighted value of fat fraction in the upper vertebral body(SFFaw),the area-weighted value of fat ratio in the lower vertebral body(IFFaw),the area-weighted value of fat fraction in the adjacent bilateral psoas major muscle and multifidus(FFaw),the T2 signal SI value of the nucleus pulposus and the Pfirrmann score were measured;The differences in SFFaw,IFFaw,FFaw of psoas major muscle and multifidus,and Pfirrmann score of each Modic of L_(5)-S_(1)intervertebral disc were compared;The correlations between SFFaw,IFFaw,FFaw of psoas major muscle and multifidus of Modic1 and 2 of L_(5)-S_(1)intervertebral disc and the T2 signal SI value of the nucleus pulposus were analyzed;The correlations between SFFaw,IFFaw,FFaw of psoas major muscle and multifidus of all endplate Modic change of L_(5)-S_(1)intervertebral disc and the Pfirrmann score were analyzed.Results There were statistically significant differences in SFFaw,IFFaw,FFaw of multifidus,FFaw of psoas major,T2 signal SI value of nucleus pulposus,and Pfirrmann score among Modic 1,Modic 2,and Modic 3 of L_(5)-S_(1)intervertebral disc(P<0.05).The values of SFFaw,IFFaw,FFaw of multifidus,and FFaw of psoas major in Modic 1 and Modic 2 of L_(5)-S_(1)intervertebral disc were negatively correlated with the T2 signal SI value of the nucleus pulposus(P<0.05),which was statistically significant.The SFFaw,IFFaw,FFaw of psoas major,and FFaw of multifidus of all endplate Modic change of L_(5)-S_(1)intervertebral disc were positively correlated with the Pfirrmann score of the intervertebral disc(P<0.05).Conclusion There are differences in the fat content of adjacent structures of each endplate Modic change of L_(5)-S_(1)intervertebral disc,and th
