Abstract:
Objective To observe the correlation between fat fraction(FF)and T2 value of multifidus muscle and Pfirrmann grade of L4-5 intervertebral disc in patients with lumbar muscle strain.Methods Totally 200 L4_5 intervertebral discs in 200 patients with lumbar muscle strain were retrospectively enrolled,including 6 cases of Pfirrmann grade Ⅰ,61 of grade Ⅱ,52 of grade Ⅲ,56 of grade Ⅳ and 25 cases of grade V.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 L4-5 intervertebral discs with different Pfirrmann grades.Multifidus muscle FF was moderately positively correlated with Pfirrmann grade of L4-5 intervertebral disc(r=0.538,P＜0.05),while T2 value was weakly positively correlated with Pfirrmann grade of L4-5 intervertebral disc(r=0.202,P＜0.05).Conclusion FF of multifidus muscle was moderately positively correlated with Pfirrmann grade of L4-5 intervertebral disc,while T2 value of multifidus muscle was weakly positively correlated with Pfirrmann grade of L4-5 intervertebral disc in patients with lumbar muscle strain.
