MR imaging of the knee.
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.
