摘　　要：目的研究对比婴幼儿发育性髋关节发育不良的MRI征象与病理,提高对婴幼儿发育性髋关节发育不良的MRI精确诊断。方法收集我院36例发育性髋关节发育不良患儿的MRI资料,对照分析FSE T1WI/T2WI、STIR、PDWI、3D FS SPGR序列对发育性髋关节发育不良组织病理改变(关节积液、关节内脂肪增生、盂唇软骨、圆韧带、髂腰肌)的观察效果。结果关节腔内脂肪堆积及积液常规T1WI/T2WI呈高信号,髋臼骨性结构STIR序列呈高信号,盂唇软骨及股骨头骨骺软骨3D FS SPGR显示较好,圆韧带和髂腰肌在关节腔内液体衬托下T2WI序列显示良好。结论MRI能全面清晰显示发育不良髋关节内关节积液、关节内脂肪增生、盂唇软骨、圆韧带、髂腰肌的病理表现,对髋臼内骨性及软骨性改变进行精确评估,为后期个体化治疗提供可靠的影像学依据。Objective To compare the MRI signs and pathology of infant developmental hip dysplasia of the Hip,and improve the accurate MRI diagnosis.Methods Collected the MRI data of 36 children with developmental hip dysplasia of the Hip in our hospital,and analyzed the effects of FSE T1WI/T2WI,ST IR,PDWI,and 3D FS SPGR sequence on the pathological changes of developmental hip dysplasia(joint effusion,intra-articular fatty hyperplasia,labrum cartilage,round ligament,iliopsoas).Results Accumulative fat and liquid in the articular cavity showed high signal on T1WI/T2WI,acetabular bone showed high signal on ST IR,cartilage of glenoid labrum and femur showed better on 3D FS SPGR,round ligament and iliopsoas showed better by the liquid in the articular cavity on T2WI.Conclusion MRI can clearly display the pathological changes of the joint effusion,intra-articular fatty hyperplasia,labrum cartilage,round ligament,iliopsoas in the dysplasia hip joint,accurately evaluate the bone and cartilage changes in the acetabulum,and provide reliable imaging basis for the later individualized treatment.
