Figure 5. 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).
