The study aims to explore the difference in relaxation time between mucoid degeneration (MD) and injured anterior cruciate ligament (ACL), and evaluate the performance of QMRI (Quantitative magnetic resonance imaging) to identify the grade of MD and injured ACL. It was concluded that T2 * value of the ACL-MD group was higher than that of the injured group, T1, T2 and T2* could be used to quantitatively identify different grades of ACL-MD (T2* may deliberately has the highest diagnostic efficacy), and the same goes for T1 to evaluate ACL injury.
