【摘要】 目的 探讨膝关节退行性骨关节病软骨下骨改变MRI分型的可行性及临床意义。方法 回顾性分析了535例病人636个关节的1551处软骨下骨改变MRI表现，将其分为4型，Ⅰ型为局限型，Ⅱ型为表浅型，Ⅲ型纵深型，Ⅳ型为囊肿型。结果 Ⅰ型911处(58.7%)；Ⅱ型165处(10.6%)；Ⅲ型302处(19.5%)；Ⅳ型173处(11.2%)。结论 MRI是膝关节退行性骨关节病软骨下骨改变影像学分型较为理想的检查方法，能够为临床制定治疗方案提供更为详细的影像学参考资料。【关键词】 膝关节；骨关节炎；软骨下骨改变

【Abstract】 Objective To evaluate the MRI classfication and clinical signification of subcartilaginous bone changes in degenerative ostroarthrosis(SBDO).Methods The author retrospectively analysed MR findings of SBDO in 1551 foci of 636 joints and divid them into four types:Ⅰtype was named as the localized type;Ⅱwas the flat-external type;Ⅲ was the deep type;Ⅳ was the cystic-change type.Results Ⅰtype were in 910 foci(58.7%),Ⅱ type in 165 foci (10.6%),Ⅲ type in 302 foci (19.5%),Ⅳ type in 173 foci (11.2%).Conclusions MRI is superior to other imaging methods in division of SBDO,and can afford more detailed imaging information. ......
