摘　　要：目的：探讨腰椎间盘退变中终板骨软骨炎的低场强MRI表现及其临床意义。方法：经临床及影像学确诊的腰椎终板骨软骨炎患者68例，其中男性37例，女性31例；年龄32～79岁，平均52岁，分析终板及邻近骨质信号改变。结果：68例病例中共累及终板186个，MRI表现为沿终板及其邻近椎体内带状或斑片状异常信号灶，按Modic分型其中Ⅰ型57个，占30．6％，Ⅱ型109个，占58．6％，Ⅲ型20个，占10．8％。好发于下腰段。所有病例均伴有椎间盘变性或突出，骨质增生54例，Schmorl结节30例，脊柱不稳16例。结论：低场强MRI能清楚显示腰椎间盘退变中终板骨软骨炎各期的信号特点，对病灶显示清晰，能准确分型，有利于临床制定合理的治疗方案。Objective： To study the low-field MRI imaging and clinical significance of end-plate osteochondritis. Methods：80 patients with end-plate osteochondritis were collected. There were 37 males and 31 females with average of 52 years（32-79）. The signal changes in end-plate and its adjacent vertebral bones were analyzed. Results： Of 68 cases,end-plate osteochondritis was identified 186. The strip or patchy abnormal signal along the end-plate and adjacent verterbral was showed on MRI. It had been classified into 3 types according to Modie classification. 57 （ 30.6% ） were Modic type Ⅰ , 109 （ 58.6% ） were Modic type Ⅱ and 20 （ 10.8 %） were Modic type Ⅲ. End-plate osteochondritis was often located at inferior segment of lumbar spine. All cases were accompanied by lumbar disc degeneration and other changes including hypcrosteogeny in 54 （79.4%）, Schmorl＇s nodule in 30 （44% ）and spinal instability in 9 （13.2 %）. Conclusion： Abnormal signal intensities of different phases for end-plate osteoehondritis can be displayed clearly by low-field MRI,whieh is helpful in treatment planning for lumbar disc degeneration.
