摘要
目的 探讨MRI对膝关节外伤的诊断价值.方法 回顾性分析410例膝关节外伤的MRI表现,其中72例行CT检查,380例同时拍摄X线平片,比较3种方法对膝关节外伤的诊断价值.结果 MRI、CT及X线对膝关节外伤的阳性检出率分别为99.02%(406/410)、70.83%(51/72)、30.00%(114/380).MRI表现分别为骨挫伤伴或不伴骨折、关节腔积液、半月板损伤、韧带损伤、关节周围软组织损伤.MRI阳性检出率明显高于CT组及X线组,组间比较差异有统计学意义(P<0.05).结论 MRI对膝关节外伤具有独特而重要的诊断价值,而且无创伤、无辐射,能够最大限度弥补X线及CT检查的不足,可作为膝关节外伤的常规检查手段.
Objective To investigate the diagnostic value of MRI imaging on detecting knee joint injury. Methods MRI manifestations of knee joint injury in 410 cases were analyzed retrospectively. Of all patients, 72 cases underwent CT scan,380 cases underwent X-ray examinations and to compare the diagnostic value of the three methods in detecting knee joint injury. Results The positive rates of MRI, CT, X-ray in detecting knee joint injury were 99.02%(406/410), 71.83%(51/71), 30.00%(114/380) respectively. Knee joint injury manifested as bone contusion or bone contusion accompanied with bone fracture, joint effusion, meniscus injury, ligament injury, para-articular soft tissue injuries with MRI. The positive rate was significantly higher than that of CT and X-ray, the difference was statistical significance. Conclusions MRI not only play a peculiar and important role in the diagnosis of the knee joint injury with non-invasion or radiation, but also can largely make up for the disadvantage of CT and X-ray,and could be used routinely.
