摘　　要：目的:探讨磁共振(MRI)和高频超声诊断儿童髋关节滑膜炎(SHC)的价值。方法:107例小儿髋部疼痛患者作为研究对象,均给予MRI和高频超声检查。分析两种检查方法对SHC的诊断价值及对不同类型SHC的鉴别价值。结果:高频超声检查与临床诊断结果的一致性高于MRI(Kappa=0.717 vs 0.586);联合检查诊断SHC的AUC为0.844,大于MRI检查的0.812(P<0.05);对不同类型SHC的鉴别诊断,高频超声检查结果与临床诊断结果的一致性(Kappa=0.813)高于MRI(Kappa=0.630);高频超声及联合检查鉴别关节囊肿胀型和关节腔积液型SHC的AUC为0.903、0.912,均大于MRI的0.815(P<0.05);MRI和高频超声对关节间隙异常、关节囊积液、关节囊肿胀、关节软骨变化的检出率分别为92.45%(49/53)、73.91%(17/23)、90.70%(39/43)、77.78%(14/18)和96.23%(51/53)、91.30%(21/23)、95.35%(41/43)、88.89%(16/18),两种检查方法对关节间隙异常等病理改变的检出率比较,差异均无统计学意义(P>0.05)。结论:MRI和高频超声联合检查对SHC具有较高的诊断价值。Objective To explore the diagnostic value of magnetic resonance imaging(MRI)and high-frequency ultrasound for synovitis of the hip in children(SHC).Methods A total of 107 children suffering from hip pain were enrolled and underwent MRI and ultrasound examinations.The value of MRI and ultrasound for diagnosing SHC and identifying different types of SHC was analyzed.Results The result consistency between high-frequency ultrasound and clinical diagnosis was higher than that between MRI and clinical diagnosis(Kappa:0.717 vs 0.586).The AUC of the combined detection for diagnosing SHC was greater than that of MRI(0.844 vs 0.812,P<0.05).For the differential diagnosis of different types of SHC,the result consistency between high-frequency ultrasound and clinical diagnosis was higher than that betweenMRI and clinical diagnosis(Kappa:0.813 vs 0.630).The AUC of high-frequency ultrasound and the combined detection for differentiation between joint swelling type and joint effusion type of SHC was 0.903 and 0.912,higher than 0.815 of MRI(P<0.05).The detection rates of joint space abnormality,joint effusion,joint swelling and joint cartilage changes were 92.45%(49/53),73.91%(17/23),90.70%(39/43),and 77.78%(14/18)when using MRI,and those were 96.23%(51/53),91.30%(21/23),95.35%(41/43),and 88.89%(16/18)when using high-frequency ultrasound.There was no significant difference in the detection rates of pathological changes such as joint space abnormality between the two methods(P>0.05).Conclusion The combined detection of MRI and high-frequency ultrasound has high diagnostic value for SHC.
