 Aims and Objectives: To study the value of USG and MRI in evaluating shoulder pain of all patients with suspected rotator cuff injury. There by, to study the disease pattern on imaging involving soft tissue and bony lesions as a cause of shoulder pain. To establish the value and limitations of common imaging techniques in studying shoulder pain related to rotator cuff injury.  Method: The study was prospectively conducted in 30 patients with pain in shoulder joint referred to Radiology Dept. at from June 2012 to July 2014. All patients were subjected to X-ray, USG and MRI.  Results: High resolution USG examination of the shoulder has a high sensitivity and specificity and accurate in the assessment of rotator cuff and ACJ pathologies. It is also cheap, can be done bed side and easily available. USG is useful in diagnosis of fluid, partial thickness tears and full thickness tears. MRI is useful in exact diagnosis of fluid, marrow edema, cartilage, ligament, tendons and labral injuries.  Conclusion: USG is as good as MRI in identifying rotator cuff injuries.
