摘　　要：目的：分析腰椎终板modic改变的影像学征象,探讨MRI在腰椎终板modic改变分型中的应用价值。方法：回顾性分析随机抽取的100例患者腰椎终板存在modic改变患者的影像学资料;所有患者均行腰椎矢状面T2WI、T1WI及T2WI反转恢复脂肪抑制（STIR）,并与X线检查进行对照,MRI检查与X线检查时间间隔在一周内,综合分析终板modic改变的信号特点及X线征象,通过双盲法进行modic改变分型并结果统一。结果：100例患者腰椎终板modic改变患者中,共诊断modic改变381处病变。所有病例按modic分型标准分四个类型,即modicⅠ型,modicⅡ型,modicⅢ型及混合型,其中将混合型又分为混合型Ⅰ-Ⅱ型及混合型Ⅱ-Ⅰ型。所有病例中,modicⅠ型共有45处,占11.81%,Ⅱ型171处,占44.88%,Ⅲ型有12处,占3.15%,混合型Ⅰ-Ⅱ型有115处,占30.18%,混合型Ⅱ-Ⅰ型,有38处,占9.97%。结论：MRI可准确地诊断腰椎终板modic改变,在腰椎终板modic改变的分型中具有较高的价值,有助于指导临床对该病的诊治。Objective To analyse the MRI and X- ray findings of lumbar endplate modic changes,investigate the diagnosis value of MRI in classification of modic changes. Method Total 100 patients of lumbar endplate modic changes were retrospectively studied,and compared with X- ray. MRI scan with T1 WI,T2WI and T2WI- FS（ STIR）. Retrospectively reviewed the MRI and X- ray findings. Results 381 cases of modic changes were found in 100 patients. Modic changes were divided into type Ⅰ,Ⅱ,Ⅲ and mixed. meanwhile,mixed type was further divided into 2 subtypes,namely type Ⅰ - Ⅱ and type Ⅱ - Ⅰ. Among them,45 cases（ 11. 81%） for type Ⅰ,171 cases（ 44. 88%） for typeⅡ,12 cases（ 3. 15%） for typeⅢ,115 cases（ 30. 18%） for mixed typeⅠ - Ⅱ,38 cases（ 9. 97%） for mixed typeⅡ - Ⅰ. Conclusion MRI can make the correct diagnosis for modic changes,which should be an important role for the classificationg of modic changes and guidance for clinic treatment.
