【摘要】：目的分析儿童肘关节骨骺损伤患者的MRI表现,探讨MRI在诊断儿童肘关节骨骺损伤中的应用价值。方法对36例5~14岁经X线检查确诊或可疑肘关节骨骺损伤儿童患者行MRI检查,检查序列包括快速自旋回波序列(TSET1WI)、脂肪抑制质子密度加权像(FS-PDWI)、三维双重回波稳态序列(3D-DESS)、关节软骨生理成像T2mapping。结果经MRI证实发生骨骺骨折28例,按Salter-Harris分型各型分布:Ⅰ型4例(14.3%),Ⅱ型11例(39.3%),Ⅲ型8例(28.6%),Ⅳ型5例(17.9%),Ⅴ型0例(0%),无骨骺骨折8例。36例儿童骨骺损伤患者中34例出现不同程度骨髓水肿,其中28例骨髓水肿出现在距离骺板1 cm范围以内,6例骨髓水肿出现在骺板1 cm范围以外,2例无骨髓水肿。骺板1 cm范围内的骨髓水肿与儿童骨骺损伤相关(P0.05)。儿童肘关节软骨骺损伤Salter-HarrisⅠ~Ⅳ型均可伴有关节软骨损伤,3D-DESS结合T2mapping可对关节软骨损伤进行良好的观察。结论 MRI对儿童肘关节骨骺损伤的诊断及分型有很高的准确性,外伤性骨髓水肿及关节软骨损伤是儿童肘关节外伤常见的伴发征象,可提示不典型的骨骺损伤,对减少儿童肘关节骨骺损伤的漏诊、误诊具有重要意义。
[Abstract]:Objective to analyze the MRI findings of children with epiphyseal injury of elbow joint and to explore the value of MRI in the diagnosis of epiphyseal injury of elbow joint in children.Methods MRI was performed in 36 children aged 5 to 14 years with epiphyseal injury of elbow joint confirmed by X-ray or suspected.The examination sequences included fast spin echo sequence TSET1WIN, fat suppression proton density weighted imaging (FS-PDWI), three-dimensional dual echo steady-state sequence (3D-DESS), and articular cartilage imaging T2mapping.Results 28 cases of epiphyseal fracture were confirmed by MRI.According to the Salter-Harris classification, there were 4 cases of type 鈪，
