摘　　要：7 T MRI可以显著提高膝关节成像的信噪比及空间分辨率,能够进行超高分辨率成像和功能代谢成像。其通过测定骨、关节软骨、半月板及韧带内的不同成分,可以很好地评估骨质疏松的程度,更早地发现关节软骨和半月板的损伤以及评估损伤修复后的表现,为骨质疏松、骨性关节炎以及半月板损伤的早期诊断与治疗提供有力的依据。就7 T MRI在膝关节病变中的研究进展进行综述。7 T MRI significantly improves the signal-to-noise ratio and spatial resolution of knee joint imaging,enabling ultra-high resolution imaging and functional metabolism imaging.By measuring different components within bones,articular cartilage,meniscus,and ligament,it can effectively assess the degree of osteoporosis,detect cartilage and meniscal injuries at an earlier stage,and evaluate post-injury repair.This provides a strong basis for early diagnosis and treatment of osteoporosis,osteoarthritis,and meniscus injury.This review summarizes the research progress of 7 T MRI in knee joint pathology.
