Fig. 4From: Can ultrasound suffice for triaging patients requiring surgical correction of rotator cuff tears—a comparative evaluation of ultrasound and magnetic resonance imagingRadiograph of the shoulder (a) shows multiple foci of calcification in the region of supraspinatus tendon. US image (b) of the same patient shows multiple calcific foci in supraspinatus tendon casting posterior acoustic shadowing. MRI PDFS axial image (c) shows tiny hypointense foci at the bursal surface (multiple small arrows) suggestive of calcific tendinosis.
