This study used 3D UTE-T2*, a novel quantitative technique with potential short-T2* relaxations to investigate T2* value in diseased Achilles tendon(AT) and correlation between T2* value and AOFAS, ATRS scores. Fifteen patients with AT disease and ten healthy controls matched sex, age, BMI were included. The results showed T2* values of insertion(INS), middle(MID), muscle-tendon junction(MTJ) and bulk region of AT in patients were statistically higher than healthy controls and negatively correlated with AOFAS, ATRS scores, which suggests UTE-T2* may be a promising marker for the detection of matrix changes in AT and give a precise guidance to clinical outcome.
