a MRI, sagittal STIR WIs: fluid signal seen at the articular surface of the musculo-tendinous junction of supraspinatous tendon (arrow). No evidence complete fiber interruption detected. b MRI, Coronal T2WIs of the shoulder showing acromio-clavicular osteoarthritis. c Static US images show partial-thickness tear of the humeral surface of the supraspinatus tendon, seen as a hypoechoic linear defect interrupting the tendon fibers (arrow). d Dynamic ultrasonography showed narrowing of the subacromial tunnel that became accentuated in stress position
