| 目的 探讨前交叉韧带(ACL)陈旧性撕裂的MRI特征及诊断价值。方法 回顾分析经关节镜证实的66例陈旧性外伤患者的MRI资料,分析其MRI表现,并诊断MRI损伤情况。结果 ACL陈旧性撕裂患者具有ACL信号异常发生率低,ACL消失及内侧半月板后角撕裂发生率高等特征。MRI诊断陈旧性ACL撕裂的灵敏度、特异度及准确度分别为90.3％、88.6％和89.4％。结论 MRI诊断ACL陈旧性撕裂仍具有较高的准确性,同时ACL陈旧性撕裂具有某些特征表现,在诊断时应注意。 |

| Objective To investigate the features and diagnostic value of magnetic resonance imaging (MRI) in diagnosing chronic tear of anterior cruciate ligament (ACL). Methods MR images of 66 patients of chronic knee trauma proved by arthroscopy were reviewed. The MRI appearance was analyzed by two radiologists, and the status of ACL was assessed finally. Results Low incidence of abnormal sign of ACL, high incidence of ACL nonvisualizative and medial menisci tear were the MRI features of chronic ACL tear. The sensitivity, specificity and accuracy of MRI in chronic ACL tear diagnosis were 90.3％, 88.6％ and 89.4％. Conclusion MRI still has high diagnostic accuracy in chronic ACL tear, and some MRI features of chronic ACL tear should be paid close attention to. |
