84 knee joints were examined by a 3-dimensional MR method and the results correlated with subsequent arthroscopy. The findings showed good demonstration of the normal anatomical structures and excellent reliability for the diagnosis of meniscus tears (sensitivity 91%, specificity 95%), cruciate ligament lesions (sensitivity 90%, specificity 99%) and serious cartilage damage (sensitivity 100%, specificity 100%). Demonstration of mild cartilage damage (sensitivity 60%, specificity 99%) was better than with a spin echo technique but is not yet optimal. It is concluded that, by using a 3-dimensional technique, time-consuming spin echo sequences can be abandoned. Significant advantages of the 3-D method are the speed of the examination, narrow section thickness, marked flexibility in contrast rendering and the ability for multiplanar reconstruction.
采用三维磁共振成像方法对84个膝关节进行检查，并将结果与随后的关节镜检查结果进行关联。结果显示，该方法能很好地显示正常解剖结构，对半月板撕裂（敏感性91%，特异性95%）、交叉韧带损伤（敏感性90%，特异性99%）和严重软骨损伤（敏感性100%，特异性100%）的诊断具有极高的可靠性。对于轻度软骨损伤的显示（敏感性60%，特异性99%）优于自旋回波技术，但仍未达到最佳状态。结论是，通过使用三维技术，可以摒弃耗时的自旋回波序列。三维方法的显著优点包括检查速度快、层厚薄、对比呈现具有显著灵活性以及多平面重建能力。
