ROLE OF MRI IN DIAGNOSIS OF ROTATOR CUFF TEAR ASSUMING ARTHROSCOPY AS GOLD STANDARD

Background- Rotator cuff tears are one of the most common causes of shoulder pain for which patients seek treatment. As in our daily work, the shoulder joint is the most frequently used, there is higher chance of having shoulder joint injury. The aim of the study is to compare the efficacy of MRI in diagnosing shoulder pathologies in comparison to arthroscopy, considering arthroscopy as the gold standard. Methods- 30 Patient with suspected rotator cuff injury patients, between 18-80 years of age was included in the study. MRI of the shoulder joint was done followed by shoulder arthroscopy. The data collected was analysed for the significant correlation between MRI of shoulder and arthroscopic findings by kappa statistics. Results- The accuracy of MRI in diagnosis of rotator cuff partial tears, was 90%, while sensitivity and specificity was 100.00%, 78.57% and positive predictive value was 84.21% and negative predictive value was 100.00% and accuracy of MRI in diagnosis of rotator cuff full tears, was 86.67%, while sensitivity and specificity was 63.64%, 100.00%) and positive predictive value was 100.00% and negative predictive value was 82.61% in our study. Conclusion- Our study demonstrates a high sensitivity and specificity for the MRI diagnosis of both partial and full thickness rotator cuff tears and good correlation with arthroscopic findings.
