This prospective study was carried out in the department of Radio-diagnosis, in a tertiary care hospital from a period of April 2017 to September 2017 to evaluate the role of high resolution USG in cases of painful shoulder joints. Total of 50 patients (29 male and 21 female) were evaluated by USG using 7.5 to 12 MHz linear array transducer with colour power Doppler facility and 3.5 to 5 MHz convex transducer with proper patient positioning and optimum techniques. In all cases proper history taking, clinical examination and supportive investigations were performed. Conventional radiographs were taken in all cases. Follow up study was divided according to clinical problems and their magnitude, consent of the patients, clinical course and treatment plan. Cases were planned for other imaging modalities like CT scan and MRI as confirmatory imaging modalities. Dynamic sonography was highly sensitive (100%) and specific (100%) for rotator cuff pathologies and most importantly it excluded other pathologies like occult fracture of humeral head, adhesive capsulitis, labral tear, infective collections which simulated rotator cuff pathologies. Hypervascularity around the affected shoulder joint in infective and inflammatory conditions was picked up by colour Doppler.
