摘要
本文探究磁共振弥散张量成像(DTI)评估足球运动致膝关节前交叉韧带(ACL)损伤分级的价值及其临床意义。选取76例足球运动致膝关节ACL损伤患者,采取自身对照研究方法,以患侧膝关节为损伤组,健侧膝关节为对照组。均行磁共振DTI检查测量表观弥散系数(ADC)、各向异性分数(FA)。结果显示,损伤组IKDC评分、Lysholm评分、FA均低于对照组,ADC高于对照组(P<0.05);患肢ADC与IKDC评分、Lysholm评分呈负相关,FA与IKDC评分、Lysholm评分呈正相关(P<0.05);ACL损伤分级Ⅲ级患者ADC高于Ⅱ级、Ⅰ级患者,且Ⅱ级患者高于Ⅰ级患者,Ⅲ级患者FA低于Ⅱ级、Ⅰ级患者,且Ⅱ级患者低于Ⅰ级患者(P<0.05);ADC与ACL损伤分级呈正相关,FA与ACL损伤分级呈负相关(P<0.05);ADC、FA诊断ACL损伤分级为Ⅱ级的曲线下面积(AUC)分别为0.738、0.759,诊断ACL损伤分级为Ⅲ级的AUC分别为0.772、0.748。磁共振DTI参数ADC、FA与足球运动致膝关节ACL损伤患者膝关节功能、损伤分级密切相关,且能无创诊断ACL损伤分级。
This paper explored the value and clinical significance of magnetic resonance diffusion tensor imaging(DTI)in assessing the grading of knee anterior cruciate ligament(ACL)injuries caused by football.76 patients with knee ACL injury caused by football sports were selected,and the self-controlled was used as research method with the affected knee joint as the injury group and the unaffected knee joint as the control group.Both the groups underwent magnetic resonance DTI to measure the apparent diffusion coefficient(ADC)and fractional anisotropy(FA).The results showed that the IKDC,Lysholm score and FA in the injury group were all lower than those in the control group,while the ADC was higher(P<0.05).The ADC of the affected limb was negatively correlated with the IKDC score and Lysholm score,and the FA was positively correlated with the IKDC score and Lysholm score(P<0.05).ADC of patients with ACL injury gradeⅢwas higher than patients with grades II and I,and patients with grade II were higher than those of patients with gradeⅠ(P<0.05).The FA of gradeⅢpatients was lower than that of gradeⅡand gradeⅠpatients,and the FA of gradeⅡwas lower than that of gradeⅠ(P<0.05).ADC was positively correlated with ACL injury grade,and FA was negatively correlated with ACL injury grade(P<0.05).The area under curve(AUC)of ADC and FA in diagnosing ACL injury with gradeⅡwere 0.738 and 0.759,respectively,and 0.772 and 0.748 for gradeⅢrespectively.Magnetic resonance DTI parameters ADC and FA are closely related to knee function and injury classification in patients with knee ACL injury caused by football sports,and also can diagnose ACL injury classification non-invasively.
