摘　　要：目的　通过对比四肢关节专用低场膝关节核磁共振图象 (MRI)与实体关节镜检查结果 ,探讨四肢关节专用低场核磁共振 (MR)检查在膝关节病变中的诊断价值。方法　自 2 0 0 1年 1 2月～ 2 0 0 3年 5月经四肢专用骨关节核磁共振检查 ,并为膝关节镜证实的 1 33例膝关节病损患者为其研究范围 ,综合对比两种检查结果。结果　四肢关节专用低场MR在膝关节病损中韧带损伤的诊断灵敏度高达 1 0 0 % ,半月板损伤最低仅为 5 5 88% (P <0 0 1 ) ;同样 ,韧带损伤诊断符合率最高 90 5 1 % ,软骨损伤最低为 82 0 9% (P <0 0 1 )。结论　核磁共振检查是临床诊断膝关节病变的一种重要、可靠的检查手段。通过采用MR特殊技术 ,提高病灶区的信号强度 ,使病变易于发现 。Objective To assess the value of dedicated magnetic resonance in diagnosing knee diseases by comparing the dedicated magnetic resonance image with the arthroscopy examination of the knee.Methods The 133 cases are collected with both the arthroscopy examination and the dedicated magnetic resonance in the knee diseases,and then we review the result.Results The diagnostic sensitivity of DMR in detecting ligament maladies was maximal to 100%.However,its sensitivity was minimal to 55 88% in menisci diseases.The diagnostic accord of DMR was highest with 90 51%,but which was lowest in cartilage focuses with 80 09%.Conclusion MR is an important and reliable method in diagnosing knee diseases.MR can identify the knee joint diseases thought improving signal intensity by using special techniques so as to avoid error.
