Figure 3. Normal anatomy as depicted on transverse T1-weighted MR arthrographic image (700/10) obtained with fat saturation after intraarticular administration of dilute gadolinium compound. Proximal portions of coracohumeral ligament (arrows), superior glenohumeral ligament (large arrowhead), and nearby long head of biceps brachii tendon (small arrowhead) are shown. Coracohumeral ligament is well defined because of adjacent contrast agent. Note normal relationship between the smaller superior glenohumeral ligament as it joins the relatively more robust coracohumeral ligament.
