摘要
目的探讨MRI对膝关节软骨损伤的诊断价值。方法回顾性分析123例（150膝）膝关节软骨损伤的MRI影像资料,并与关节镜或手术对照。结果本组123例（150膝）900个软骨面中,MRI诊断膝关节软骨损伤的总敏感度为99.15%,特异度为98.35%,准确度为98.67%,阴性预测值为99.44%,阳性预测值Ⅰ∽Ⅳ级分别为82.35%、87.7%、94.4%、100%。与关节镜结果相比,MRI诊断膝关节软骨损伤一致性佳（Kappa=0.949）,差异无统计学意义（p〈0.05）。结论 MRI能较准确判断膝关节软骨损伤的部位、范围及程度,为临床治疗方案的确定提供重要依据,是软骨损伤的最佳检查方法。
Objective To study the diagnostic value of MRI on cartilage injury of knee joint. Methods The MRI data of 123 patients with cartilage injury of knee joint were analyzed respectively and were compared with results of arthroscope or operation. Results Results The total cartilage injury of knee joint presented with 99.15% sensitivity,98.35% specificity and 98.67% accuracy, 99.44% negative predictive value, stage I~Ⅳ of positive predictive value was 82.35%、87.7%、94.4%、100%.The MRI result was similar to the arthroscope result（Kappa=0.949 p=0.000）. Conclusions MRI demonstrated the location, range and injury degree of the cartilage injury exactly, which may be the best examination for cartilage injury.
