Abstract
The knee is the largest flexion joint of the human body. Its structure is complex, for instance, it can withstand strong leverage, but nevertheless it is extremely vulnerable. In recent years, with the changes in people’s lifestyles and increasing pressure in work and life, the risk of knee joint injury, especially the risk of meniscus and articular cartilage damage, has increased significantly. Arthroscopy is the golden standard for the diagnosis of knee injury, but it has certain limitations in the early and convenient diagnosis of the injury. Moreover, although this examination is an invasive operation, it may causes a certain degree of secondary damage to the patient during the examination. Magnetic resonance imaging (MRI) T2 mapping technology is a new MRI technology that is developed in recent years. It can indirectly reflect the structures and histological composition of articular cartilage before the morphological changes of articular cartilage. Therefore, this technique is of great significance for early knee injury diagnosis. In this article, we reviewed the basic physiological and pathological changes before and after knee injury, as well as the conventional knee joint technique, focusing on the imaging principle and diagnostic advantages of the T2 mapping sequence and comparing it with conventional MRI sequences.
