In this chapter, we show how the normal rotator cuff tendons and muscles look like on MRI and ultrasonography. By looking at the inclination of the superior surface of the greater tuberosity (footprint of the rotator cuff), we can identify the superior and middle facets, and accordingly we can identify the supraspinatus and infraspinatus tendons as well. The rotator cuff tendons appear as a homogeneous thick tendinous band with low signal on MRI and the fibrillar pattern on ultrasound. The intramuscular tendons of the rotator cuff muscles and the deltoid are clearly depicted on MRI as a low signal band inside the muscle belly.
