【摘要】：目的探讨与前交叉韧带(ACL)损伤相关性最大的MRI征象。方法回顾性分析124例患者的MRI图像,分别计算5个征象诊断ACL损伤的敏感性、特异性及准确性;通过Logistic后退回归法,分析与ACL损伤相关性最大的MRI征象。结果 ACL中断诊断ACL损伤的敏感性、特异性及准确性分别为13.8%、97.3%、38.7%;ACL信号或(和)走行异常诊断ACL损伤的敏感性、特异性及准确性分别为85.1%、91.9%、87.1%;PCL指数诊断ACL损伤的敏感性、特异性及准确性分别为51.7%、27.0%、44.4%;胫骨前移诊断ACL损伤的敏感性、特异性及准确性分别为62.1%、94.6%、71.7%;半月板后角裸露征诊断ACL损伤的敏感性、特异性及准确性分别为46.0%、92.0%、59.7%。与ACL损伤的相关性由大至小:ACL信号或(和)走行异常;ACL中断;胫骨前移;半月板后角裸露征;PCL指数。结论 ACL走行及信号异常是ACL损伤相关性最大的因素,胫骨前移是ACL损伤相关性最大的间接征象。
[Abstract]:Objective to investigate the MRI signs with the greatest correlation with anterior cruciate ligament (ACL) injury. Methods the sensitivity, specificity and accuracy of 5 signs in the diagnosis of ACL injury were analyzed retrospectively. Results the sensitivity, specificity and accuracy of ACL interruption in the diagnosis of ACL injury were 13.897. 3% and 38.7%, respectively. The specificity and accuracy were 85.1 / 91.9 and 87.1respectively, and the sensitivity, specificity and accuracy were 51.727.0 and 44.4, respectively; the sensitivity, specificity and accuracy of tibial forward movement in diagnosing ACL injury were 62.1 / 94.60.The sensitivity of posterior horn nudity of semilunar plate in the diagnosis of ACL injury was 62.1 / 94.67.The sensitivity of the posterior horn nudity of semilunar plate in the diagnosis of ACL injury was significant. The specificity and accuracy were 46.0 / 92.0 and 59.7, respectively. The correlation with ACL damage was interrupted from large to small to small to small. Conclusion ACL walking and signal abnormality are the most important factors in the correlation of ACL injury, and tibia forward movement is the most indirect sign of ACL injury correlation.
