【摘要】 目的　回顾性分析半月板不同程度损伤的MRI表现。方法　对 86例可能半月板损伤患者的 97个膝关节 194个内外侧半月板的MRI表现和关节镜进行对照研究与分析 ,根据半月板内部MRI信号特征 ,将半月板损伤分为Ⅰ～Ⅲ度。结果　在 194个半月板信号中发现 16 0个半月板信号异常 ,Ⅰ度损伤 31个 ,Ⅱ度损伤 5 8个 ,Ⅲ度损伤 71个。以关节镜检查结果为标准 ,MRI诊断半月板撕裂的敏感性为 90 .2 7% ,特异性为 95 .0 9% ,准确性为 88.14 % ,阳性预测值为 91.5 5 % ,阴性预测值为94.31%。结论　MRI是一种无创伤、能准确诊断半月板损伤以及取代创伤性关节镜检查的较好方法。更多还原

【Abstract】 Objective To analyse the MRI findings of various meniscus injuries of knee joint retrospectively.Methods MRI manifestations of 86(97 knees)suspected menisci injures by clinical were analysed and compared with the findings through arthroscopy.The menisus injuries were classified into grade Ⅰto Ⅲ according to the signal features of meniscus on MR imaging.Results In our study,grade Ⅰ was 31 ,grade Ⅱ was 58,grade Ⅲ was 71.Taking the result through arthroscopy as standard,the sensitivity,sepecificity,accuracy of predictive value,positive predictive value and negative predictive value of MRI were 90.27%,95.09%,88.14%,91.55%and 94.31% respectively.Conclusion MR imaging is non-invasive and accurate to evaluate the meniscus injury of the knee joint and is a better way to replace the traumatic arthroscopy.更多还原
