Synopsis

Keywords: Musculoskeletal: Joints

MRI provides unparalleled evaluation of regional joint anatomy. The structural composition of tissues is reflected in both morphologic and quantitative MRI, which has links to material properties and response to mechanical load. This talk will discuss knee anatomy with a focus on articular cartilage, fibrocartilaginous meniscus, and ligament/tendon, drawing insights into tissue relaxometry as a function of histopathology and function. Imaging data provide information about response to injury and repair, and quantitative evaluation of ACL reconstruction, the repaired meniscus, and tendinopathy will further be provided, with a focus on T2, T2* and T1rho mapping, with and without applied load.
