Abstract: The changes of MR T2 mapping quantitative parameters in exercise-induced rotator cuff tear (RCT) patients and their relationship with the prognosis and functional outcome were explored in this paper. A total of 80 patients with exercise-induced RCT were selected as the research objects. All of them underwent MRI routine scanning and MR T2 mapping scan, and divided into group A (level Ⅰ, n=25), group B (level Ⅱ, n=39), and group C (level Ⅲ, n=16) according to the RCT classification. Through comparative analysis, it was found that the medial, lateral, and intermediate T2 values of the supraspinatus tendon in group A were lower than those in groups B and C, and group B was lower than that of group C (P<0.05); the medial, lateral, and middle T2 values of the supraspinatus tendon were all lower than the RCT grading was positively correlated (P<0.05); the medial, lateral, and intermediate T2 values of the supraspinatus tendon and the upper extremity Disability of arm shoulder and hand (DASH) scores of the RCT patients were lower than the preoperative, subjective shoulder value (SSV) scores were higher than preoperative (P<0.05); the medial, lateral, and middle ΔT2 values of supraspinatus tendon before and after surgery were positively correlated with ΔSSV and ΔDASH scores (P<0.05). It can be seen that the quantitative parameters of MR T2 mapping are positively correlated with the RCT grading of patients with exercise-induced RCT, and the change values of each parameter are closely related to the prognostic function outcome.
