摘　　要：目的观察腰肌劳损患者多裂肌脂肪分数(FF)及T2值与L 4-5椎间盘Pfirrmann分级的相关性。方法回顾性纳入200例腰肌劳损患者共200个L 4-5椎间盘,包括PfirrmannⅠ级6个、Ⅱ级61个、Ⅲ级52个、Ⅳ级56个、Ⅴ级25个。基于改良DIXON定量技术(mDIXON-Quant)及T2 mapping计算多裂肌FF及T2值,比较不同Pfirrmann分级椎间盘之间上述参数的差异,并分析各参数与椎间盘Pfirrmann分级的相关性。结果不同分级L 4-5椎间盘之间,左侧、右侧及双侧多裂肌FF,以及左侧及双侧多裂肌T2值差异均有统计学意义(P均<0.05)。多裂肌FF与L 4-5椎间盘Pfirrmann分级呈中度正相关(r=0.538,P<0.05),其T2值则与L 4-5椎间盘Pfirrmann分级呈弱正相关(r=0.202,P<0.05)。结论腰肌劳损患者多裂肌FF与L 4-5椎间盘Pfirrmann分级呈中度正相关;多裂肌T2值则与L 4-5椎间盘Pfirrmann分级呈弱正相关。Objective To observe the correlation between fat fraction(FF)and T2 value of multifidus muscle and Pfirrmann grade of L 4-5 intervertebral disc in patients with lumbar muscle strain.Methods Totally 200 L 4-5 intervertebral discs in 200 patients with lumbar muscle strain were retrospectively enrolled,including 6 cases of Pfirrmann gradeⅠ,61 of gradeⅡ,52 of gradeⅢ,56 of gradeⅣand 25 cases of gradeⅤ.Based on modified DIXON quantification(mDIXON-Quant)and T2 mapping,FF and T2 value of multifidus muscle were calculated and compared among intervertebral discs with different Pfirrmann grades,and the correlations between the above parameters and Pfirrmann grade of intervertebral disc were analyzed.Results Significant differences of left,right and bilateral multifidus muscles FF,as well as of T2 values in left and bilateral multifidus muscles were found among L 4-5 intervertebral discs with different Pfirrmann grades.Multifidus muscle FF was moderately positively correlated with Pfirrmann grade of L 4-5 intervertebral disc(r=0.538,P<0.05),while T2 value was weakly positively correlated with Pfirrmann grade of L 4-5 intervertebral disc(r=0.202,P<0.05).Conclusion FF of multifidus muscle was moderately positively correlated with Pfirrmann grade of L 4-5 intervertebral disc,while T2 value of multifidus muscle was weakly positively correlated with Pfirrmann grade of L 4-5 intervertebral disc in patients with lumbar muscle strain.
