摘　　要：目的 探讨前交叉韧带（ACL）损伤患者实施磁共振成像（MRI）诊断的临床意义,为临床选择诊断方式提供参考.方法 选择ACL带损伤疑似患者42例,所有患者进行关节镜诊断及MRI诊断,对比诊断结果.结果 43膝ACL疑似损伤,关节镜下诊断11膝正常,损伤32膝;MRI影像学诊断9膝正常,损伤34膝;关节镜下诊断与MRI诊断结果相符39膝,不符合4膝;MRI诊断灵敏度为96.88％,特异度为72.73％,假阳性率为6.98％,假阴性率为2.33％,准确率为90.70％.结论 MRI诊断ACL带损伤准确率较高,假阳性及假阴性诊断需改变扫描方法并结合其他检查以避免误诊.Objective To investigate the clinical value of MRI in diagnosis of anterior cruciate ligament,to provide a reference for clinical diagnosis.Methods 42 suspected patients with anterior cruciate ligament were selected,MRI and arthroscope were used in all patients,results were compared.Results 11 cases of 43 suspected ACL knees were detected normal under arthroscope,the other 32 cases were injured,under MRI 9 cases were detected normal.39 cases had same results under MRI and arthroscope;the sensitivity of MRI was 96.88%,the specificity rate was 72.73%,the false positive rate was 6.98%,the false negative rate was 2.33%,the accuracy rate was 90.70%.Conclusion MRI is a accurate way to diagnose anterior cruciate ligament,better scan methods and other diagnosis should be combined to decrease false results.
