Abstract：T2* mapping,a quantitative MRI technique based on multi gradient-echo sequences,has been widely used in the structurally complex musculoskeletal system due to its advantages of rapid imaging,non-invasive acquisition,and high spatial resolution.It is primarily employed to evaluate metabolism and blood perfusion changes in skeletal muscle during exercise,degeneration and load response of articular cartilage,degenerative changes of spinal intervertebral discs and osteoporosis,as well as injury and postoperative repair processes of ligaments and tendons.This technique demonstrates high sensitivity in detecting changes in tissue composition,water content,and collagen structure.This review summarizes the principles of T2* mapping sequences and recent advancements in their applications for musculoskeletal system assessment,and discusses prospects for clinical use.
