摘　　要：目的:探讨MRI对半月板损伤的诊断价值及其对临床治疗的指导意义。方法:回顾性分析196个半月板损伤的MRI表现和关节镜表现。根据MRI信号改变将半月板损伤分为Ⅰ、Ⅱ、Ⅲ级,并与关节镜下表现进行对比分析。结果:以关节镜下表现为标准,MRI诊断准确率在Ⅰ级信号组86.96%,Ⅱ级信号组88.46%,Ⅲ级信号组90.91%,总体诊断准确率91.33%。结论:半月板损伤MRI与关节镜诊断一致性较高,有较高诊断价值。Objective： To explore the accuracy of MRI in the diagnosis of meniscus injuries and its instructional value for clinical management.Methods： MRI and arthroscopie imaging of 196 meniscus were retrospectively analyzed. According to the signal features of meniscus on MRI imaging, the meniscus injuries were classified into grade Ⅰ to grade Ⅲ then the MRI features were compared with arthroscopic imaging respectively.Results：Depending on the exploration in arthroscopy, the accurate rate of diagnosis for grade Ⅰ was 86.96%（20/23）,grade Ⅱ 88.46%（46/52）,grade Ⅲ 90.19%（110/121）. The total accurate rate of MRI for diagnusis of meniscus in juries was 91.33 % （ 179/196 ）. Conclusion： Manifestations of MRI of meniscus injuries accord with that of arthruscopy MRI and arthroscopr are useful in the diagnosis of meniscus injuries.
