A search of the available literature was performed and the role of MR imaging of the knee is discussed. Based on this search the authors concluded that MR has a high sensitivity in detecting any abnormalities in the knee but it does not have the same diagnostic accuracy as a clinical investigation performed by a trained knee specialist when all knee injuries are taken together. It does lead to a decrease in the number of surgical interventions due to its high negative predictive value. For the detection of meniscal injury, MR has the same accuracy as arthroscopy and should be performed in order to avoid unnecessary surgical interventions. A negative MR also obviates further investigation in suspected cartilage damage. This is not true for anterior and posterior cruciate ligament problems where MRI is less accurate than clinical investigation.
我们对现有文献进行了检索，并讨论了膝关节磁共振成像（MR）的作用。基于此次检索，作者得出结论：MR在检测膝关节任何异常方面具有高灵敏度，但当综合考虑所有膝关节损伤时，其诊断准确性不如由训练有素的膝关节专科医生进行的临床检查。由于其高阴性预测价值，它确实导致了手术干预数量的减少。对于半月板损伤的检测，MR与关节镜检查具有相同的准确性，应进行MR检查以避免不必要的手术干预。MR检查结果为阴性也可避免对疑似软骨损伤进行进一步检查。对于前交叉韧带和后交叉韧带问题，情况并非如此，在这些情况下MRI的准确性低于临床检查。
