•To compare diagnostic efficacy of ultrasound and MRI in detection of rotator cuff tears with surgical findings (arthroscopy or open surgery) as gold standard. •To describe the distribution of rotator cuff tears in terms of demographics, symptomatology and associated abnormalities among the study population.

PATIENT SELECTION: •Prior ultrasound screening was done for every patient who came for MRI shoulder with clinical suspicion of rotator cuff tear. INCLUSION CRITERIA : •All clinically suspicious cases of rotator cuff tear, for whom prior ultrasound screening and MRI study was done and who later underwent surgery (arthroscopy/open surgery). EXCLUSION CRITERIA : •Contraindicated to MRI. •Any prior shoulder surgery of same side before imaging. Of 75 patients who were diagnosed with rotator cuff tear, only 56 were included in study group in whom arthroscopy/open...

•USG- First line investigation. •MRI is the modality of choice and second line non invasive test to confirm the diagnosis. •Dominant arm, increasing age, male gender and symptoms of pain and restriction of movement were commonly associated with rotator cuff tears. Both imaging has the potential to positively affect the outcome, morbidity in these patient.
