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。

关 键 词:椎间盘退变  终板骨软骨炎  磁共振成像

Abstract: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 typeⅠ,45(33.1%) were Modic typeⅡ,14(10.3%) were Modic typeⅢ.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.
Keywords:disc degeneration  end-plate osteochondritis  magnetic resonance imaging
