低场强MRI对膝关节骨挫伤的诊断分析

摘要

目的：总结低场强M RI在膝关节骨挫伤诊断中的应用价值和意义。方法：收集了2008年以来我院检查的66例膝关节骨挫伤患者的M RI影像学资料，回顾性分析膝关节骨挫伤的影像学表现。结果：M RI能明确诊断66例患者的膝关节骨挫伤，并能显示部分病例伴有的其他损伤：半月板损伤36例，韧带损伤19例，X线平片未见的隐性骨折7例，关节腔积液61例，关节面软骨损伤10例，软骨骺板损伤3例。结论：低场强M RI对膝关节骨挫伤的显示非常敏感，并能准确判断其附属结构的损伤，明确损伤的部位和程度，从而为临床早期诊断、治疗以及对愈后的评估提供较确切的依据。%Objective :To discuss the usefulness of low field joint MRI in bone contusion of knee joint .Methods:A ret-rospective view of 66 consecutive MRI examinations for knee trauma which was confirmed by clinic was conduct .Re-sults:66 lesions of bone contusion were documented in these cases ,and also view the other lesions :meniscus injury(36 cases) ,ligament injury(19 cases) ,occult bone fracture(7 cases) which were not manifested with X-ray ,joint effusion (61 cases) ,articular cartilage injury(10 cases) ,epiphyseal plate injury(3 cases) .Conclusion:MRI can clearly show vari-ous appearances of knee joint in jury and have instructional significance for clinic .
