From: Role of dynamic ultrasound versus MRI in diagnosis and assessment of shoulder impingement syndrome
a MRI, sagittal STIR WIs: fluid signal is seen filling the gap as a result of full-thickness tear of the supraspinatous tendon (arrow), also shows acromio-clavicular osteoarthritis changes. b MRI, sagittal T2WIs of the shoulder showing focal fiber interruption of the subscapularis tendon with fluid signal noted (arrow). c MRI, axial T2 of the shoulder shows marked fluid signal along the sheath of long head of biceps tendon. d Static US images show distension of long head of biceps tendon sheath by hypoechoic fluid. e Static US shows hypoechoic linear defect interrupting the fibers of supraspinatous tendon (arrow)
