“…In this study, US correctly diagnosed 81.2% cases of PTT of rotator cuff with sensitivity, specificity, and accuracy of 78.1%, 94.4% and 84%, respectively, compared to MRI. Previous studies 9,15,22,26,28,31,33,40,[42][43][44][45][46] with MRI as reference standard have found sensitivity, specificity, and accuracy of US ranging from 12.5-94.7%, 67.9-100%, and 78-97.3%, respectively for diagnosing a partial thickness RCT. Further, in this study 96% cases of rotator cuff tendinosis were correctly diagnosed by US with sensitivity, specificity, and accuracy of 84%, 87.5%, and 86%, respectively.…”
