58 knee joints of 57 patients were examined via magnetic resonance tomography. Measurements were effected at 1.5 tesla using SE sequences in multilayer and dual-echo technique. Arthroscopic reference findings were available from all patients, comparison between arthroscopy and MRT in 93 menisci resulted in the present patient group in a negative predictive value of 97.4% and in a positive predictive value of 88.6%. Degenerative changes of the rupture-free menisci could be diagnosed via MRT in 15 cases. Besides the frequently observed central degeneration there were also superficial degenerations and fibrovascular proliferations. MRT can be recommended for pre-arthroscopy screening in suspected meniscus lesions on the basis of the methods of measurement and evaluation presented in this paper.
对57例患者的58个膝关节进行了磁共振断层扫描检查。在1.5特斯拉下使用多层和双回波技术的SE序列进行测量。所有患者均有关节镜参考结果，在本患者组中，对93个半月板的关节镜检查和磁共振成像比较得出阴性预测值为97.4%，阳性预测值为88.6%。通过磁共振成像可诊断出15例无破裂半月板的退行性改变。除了常见的中央退变外，还存在表面退变和纤维血管增生。基于本文提出的测量和评估方法，磁共振成像可推荐用于疑似半月板损伤的关节镜检查前筛查。
