Abstract：Objective To explore the diagnostic value of MR imaging for different types of acute shoulder injuries. Methods A retrospective analysis was conducted on the clinical data of 80 patients with acute shoul-der injuries who were treated at Xinghua City Hospital of Traditional Chinese Medicine from January 2022 to De-cember 2023. Using arthroscopy as the gold standard,the sensitivity,specificity,and accuracy of MR imaging in diagnosing acute shoulder injuries were analyzed,and Kappa consistency tests were performed. Results Among the 80 patients,the sensitivity,specificity,and accuracy of MR imaging for diagnosing rotator cuff injuries were 91.53％ (54/59),80.95％ (17/21),and 88.75％ (71/80),respectively. The consistency of MR imaging diagnosis for rotator cuff injuries was Kappa=0.714. For shoulder impingement syndrome,the sensitivity,specificity,and accura-cy were 88.24％ (15/17),95.24％ (60/63),and 93.75％ (75/80),respectively,with a consistency of Kappa=0.817. For labral tears,the sensitivity,specificity,and accuracy were 75.00％ (3/4),98.68％ (75/76),and 97.50％ (78/80),respectively,with a consistency of Kappa=0.737. Conclusion MR imaging demonstrates high sensitivity,speci-ficity,and accuracy in diagnosing rotator cuff injuries,shoulder impingement syndrome,and labral tears,with diag-nostic performance comparable to arthroscopy,thus holding significant clinical value.
