摘　　要：目的探讨膝关节骨梗死的X线、MRI特征。方法收集经病理及临床随访证实的的膝关节骨梗死17例,所有病例均行X线、MRI检查,分析其X线、MRI特征。结果膝关节骨梗死早期、中期X线可表现为正常或骨质疏松,晚期表现为地图样钙化;早期、中期、晚期膝关节骨梗死MRI分别表现为三环征、双线征、单环征。结论 MRI能反应膝关节各期骨梗死的病理变化,晚期骨梗死有特征性X线表现,对于早期膝关节骨梗死患者,应首选MR检查。Objective To explore the imaging features of bone infarction of the knee with X-ray and MRI.Methods 17 cases of the bone infarction proved by clinical manifestation and pathology were collected.All cases underwent X-ray and MRI examination.The X-ray and MRI features were analyzed.Results The knee joint bone infarction in early and middle stage,x-rays can show the normal or osteoporosis,advanced performance for geographic calcification.Early,mid,and late knee bone infarction MRI were shown as triple line sign,double line sign,and single line sign.Conclusion MRI can response the knee joint bone infarction every period of pathological changes,the late bone infarction has characteristic X-ray manifestation,for early stage knee joint bone infarction patients,should be the preferred MR examination.
