摘要
目的观察MR T2 mapping评估粘连性肩关节囊炎(ACS)并进行分期的价值。方法前瞻性对66例ACS患者(ACS组)及30名健康人(对照组)行肩关节MR常规序列、质子密度加权成像及T2 mapping扫描,比较组间及不同分期间喙肱韧带及腋囊厚度、T2值;绘制受试者工作特征曲线,以曲线下面积(AUC)评估各参数评估ACS及进行分期的效能。结果ACS组喙肱韧带及腋囊厚度、T2值均大于对照组(P均<0.05)。各期ACS喙肱韧带及腋囊T2值差异均有统计学意义(P均<0.05);Ⅲ期ACS喙肱韧带及腋囊T2值小于Ⅰ、Ⅱ期ACS(P均<0.05),Ⅱ期ACS腋囊T2值大于Ⅰ期ACS(P<0.05),T2值与Ⅰ期喙肱韧带差异无统计学意义(P>0.05)。以喙肱韧带厚度、喙肱韧带T2值、腋囊厚度及腋囊T2值评估ACS的AUC分别为0.985、0.999、0.996及0.967。喙肱韧带T2值区分Ⅰ期与Ⅱ期ACS效能不高(AUC为0.488),而区分Ⅱ、Ⅲ期ACS效能甚高(AUC为0.986);腋囊T2值区分Ⅰ、Ⅱ期以及Ⅱ、Ⅲ期ACS的AUC分别为0.752及0.975。结论MR T2 mapping可用于无创评估ACS及其分期。
Objective To observe the value of MR T2 mapping for evaluating and dividing stages of adhesive capsulitis of shoulder(ACS).Methods Sixty-six patients with ACS(ACS group)and 30 healthy subjects(control group)were prospectively enrolled.MR scanning of conventional sequences,proton density weighted imaging and T2 mapping of shoulder were performed.The thickness and T2 values of coracohumeral ligament and axillary recess were compared between groups and among different stages of ACS.The receiver operating characteristic curve was drawn,and the area under the curve(AUC)was used to evaluate the efficacy of each parameter for assessing ACS and dividing stages.Results The thickness and T2 values of coracohumeral ligament and axillary recess in ACS group were higher than those in control group(all P<0.05).Significant differences of T2 values of coracohumeral ligament and axillary recess were found among different stages of ACS(all P<0.05).T2 values of coracohumeral ligament and axillary recess in stage Ⅲ ACS were lower than those in stage Ⅰ and stage Ⅱ ACS(all P<0.05).T2 value of axillary recess in stage Ⅱ ACS was higher than that in stage Ⅰ ACS(P<0.05),while no significant difference of T2 values of coracohumeral ligament between stage Ⅰ and stage Ⅱ ACS(P>0.05).The AUC of coracohumeral ligament thickness,coracohumeral ligament T2 value,axillary recess thickness and axillary recess T2 value for evaluating ACS was 0.985,0.999,0.996 and 0.967,respectively.T2 value of coracohumeral ligament showed low efficacy for differentiating stage Ⅰ and Ⅱ ACS(AUC of 0.488),but high efficacy for distinguishing stage Ⅱ and Ⅲ ACS(AUC of 0.986).The AUC of T2 value of axillary recess for differentiating stage Ⅰ from stage Ⅱ and Ⅱ from Ⅲ ACS was 0.752 and 0.975,respectively.Conclusion MR T2 mapping could be used for noninvasive evaluating and dividing stages of ACS.
