It has been previously demonstrated that MRI can show the knee joint non-invasively and without radiation. Forty-two patients with lesions of the knee were examined using 1.5 Tesla and flexible surface coils. The findings were compared with those of arthroscopy, arthrography and, where possible, with those at surgery. For the evaluation of cruciate ligament injuries, MRI proved to have a sensitivity of 100% and a specificity of 82% with an overall accuracy of 92%. Thirty-nine cruciate ligaments were correctly evaluated. Three times a false positive diagnosis was made. Examination of the menisci was less reliable. Sensitivity was 88% and specificity was 83% with an overall accuracy of 94%. Fifteen meniscus lesions were correctly diagnosed. Three times a false positive and twice a false negative diagnosis was made. Four of the five incorrect diagnoses concerned the posterior horn of the meniscus and three were situated laterally.
先前已证明，磁共振成像（MRI）能够无创且无辐射地显示膝关节。42例膝关节损伤患者接受了1.5特斯拉及柔性表面线圈检查。将检查结果与关节镜检查、关节造影检查结果进行比较，并在可能的情况下与手术结果进行比较。对于交叉韧带损伤的评估，MRI的敏感性为100%，特异性为82%，总体准确率为92%。39条交叉韧带得到正确评估。出现了3例假阳性诊断。半月板检查的可靠性较低。敏感性为88%，特异性为83%，总体准确率为94%。15例半月板损伤得到正确诊断。出现了3例假阳性和2例假阴性诊断。5例错误诊断中有4例涉及半月板后角，3例位于外侧。
