From the case: Shoulder anatomy on ultrasound
Supraspinatus tendon Supraspinatus tendon: a transverse view of a normal supraspinatus tendon is shown in this image. Note the 3 major tissue layers of subcutaneous fat, deltoid muscle and tendon ruling out a large, full-thickness tear of the tendon. Also note the relatively homogeneous texture and brightness and the smooth contour of the tendon ruling out degeneration (tendinosis) and more subtle tearing. The bursa is thin and anechoic, the articular cartilage is thick and smooth and surface of the greater tuberosity is regular.
