Left: medial; right: lateral; bottom of screen: deep; top of screen: superficial.
(A) Pathologic thickening of the supraspinatus tendon (8 mm between caliper marks [+]). Note the variations in light-dark and in consistency of the tendon compared with the normal tendon in (B). These findings are consistent with tendinopathy.
(B) Normal tissues for comparison.
(C) Probe position for obtaining these ultrasound images.
