Comparison Between High Resolution Ultrasound And MRI In The Evaluation Of Rotatorcuff Injuries.

Introduction: The shoulder joint's stability is largely provided by the rotator cuff muscles and tendons, crucial for dynamic stabilization. Pathologies in these muscles are major causes of shoulder pain and disability. USG and MRI are non-invasive, radiation-free imaging methods with high sensitivity for diagnosing rotator cuff disorders, offering complementary diagnostic insights. Methodology: Patients presenting with complaints of pain in shoulder joint, restricted movements or clinical suspicion of RC disorders were referred to Radiodiagnosis Department of Muzaffarnagar Medical college. In this study, 30 patients of both genders were studied in age between 20 to 60 years. HRUSG followed by MRI of the affected side shoulder was performed. Result: In this study, 60% of males and 40% of females were affected, primarily in the 41-50 age group. The supraspinatus tendon was most commonly impacted, with MRI outperforming USG in detecting pathologies. USG showed high specificity and moderate sensitivity and accuracy in identifying rotator cuff tears, particularly full-thickness tears (FTT). However, USG was less effective in detecting infraspinatus and subscapularis tendon issues. Both imaging modalities have limitations, with USG unable to properly evaluate abnormalities of the glenoid labrum, various ligaments, and bones. Tears were associated with subacromial-subdeltoid and Sub coracoid bursitis. Conclusion: Clinical examination, X-ray, and CT scans offer limited insight into shoulder joint pathologies, particularly for soft tissues like the rotator cuff. HRUSG, being affordable, non-invasive, and real-time, is the first-line diagnostic tool for screening rotator cuff disorders. MRI serves as a problem-solving modality, offering detailed evaluation in complex cases involving glenoid labrum, ligaments, bones, and muscle atrophy, especially when USG results are inconclusive.
