Figure 13. Arthroscopically confirmed injury with fraying of superior glenohumeral ligament. Transverse T1-weighted MR arthrographic image (700/10) obtained with fat saturation after intraarticular administration of dilute gadolinium compound. Superior glenohumeral ligament (black arrow) is thickened and slightly irregular. A normal superior glenohumeral ligament is usually smaller than the coracohumeral ligament (white arrow).
