Magnetic resonance imaging (MRI) is the modality of choice for the imaging evaluation of the knee. Moreover, advances in magnetic field strength, gradient strength, and coil design have facilitated the development of new pulse sequences, which have transformed knee MRI from routine morphologic imaging to metabolic imaging and imaging of ultrastructure. This article will review MRI of meniscal injury and anterior cruciate ligament injury, as well as new developments in MRI of the knee such as 3 T imaging and techniques for cartilage imaging such as T2 mapping, T1ñ, and delayed gadolinium-enhanced MRI of cartilage.
磁共振成像（MRI）是膝关节成像评估的首选方式。此外，磁场强度、梯度强度和线圈设计的进步推动了新脉冲序列的发展，这些新脉冲序列已将膝关节MRI从常规形态学成像转变为代谢成像和超微结构成像。本文将综述半月板损伤和前交叉韧带损伤的MRI，以及膝关节MRI的新进展，如3T成像和软骨成像技术，如T2映射、T1ρ和延迟钆增强软骨MRI。
