This image demonstrates a longitudinal view of the biceps tendon. The proximal intracapsular end of the long biceps tendon (T) is displayed on the observer’s left. Within the normal tendon, a distinct fibrillar pattern is noted (arrow). D = deltoid muscle.

With the transducer placed over the long axis of the deltoid muscle (D), note the longitudinal striations (upper arrows) of the fibrofatty septa in between the muscle bundles. Supraspinatus tendon (S) is displayed in its long axis deep to the deltoid. The tendon rests on the bright echogenic surface of the proximal humerus. The humeral head shows on the medial aspect (observer’s right) and the greater tuberosity more laterally. The anatomic neck is recognized on the groove (lower arrow) between these bone surfaces.

With the transducer turned perpendicular to the position in Figure 4, the examination of the supraspinatus (S) is completed with transverse views of the cuff. The deltoid muscle (D) is separated from the supraspinatus by alternating hypo- and hyperechoic lines, representing bursa and peribursal fat. The echogenic supraspinatus rests on hypoechoic hyaline cartilage over the echogenic humeral head surface (c).
