腰椎间盘退变中终板骨软骨炎的低场MRI诊断

摘要

目的 探讨低场MRI对腰椎间盘退变中终板骨软骨炎的诊断价值.方法 对60例腰椎间盘退变中终板骨软骨炎的低场MRI表现进行回顾性分析.结果 60例患者共累及终板136个,按Modic分型,Ⅰ型77个(56.6%);Ⅱ型45个(33.1%);Ⅲ型14个(10.3%).多发累及49例(81.7%);单发11例(18.3%).好发于下腰段,累及双侧终板多见.结论 低场MRI能准确显示腰椎间盘退变中终板骨软骨炎的部位、范围及各期信号特点,为临床制定合理的治疗方案提供了有力依据.%Objective To study the value of low-filed MRI diagnosis of end-plate osteochondritis in lumbar disc degeneration.Methods Low-filed MRI features of 60 cases suffered from end-plate osteochondritis in lumbar disc degeneration were retrospectively analyzed.Results Sixty end-plate with osteochondritis were into 3 type according to Modic classification,77 (56.6 ％ )were Modic type Ⅰ ,45 ( 33.1％ ) were Modic type Ⅱ, 14 ( 10.3％ ) were Modic type Ⅲ.There were 49 cases( 81.7％ ) suffered from multiple end-plate osteochondritis and 11 (18.3％) suffered from single end-plate osteochondritis.End-plate osteochondritis was often located at inferior segment of lumbar spine, the twin side of end-plate affected were the most common.Conclusion The low-field MRI can accurately demonstrate the location , extent and abnormal signal intensities of different phases of end-plate osteochondritis , which was foundations in the treatment planning for lumbar disc degeneration.
