MR arthrography of the shoulder: glenohumeral ligaments.

Knowledge of the anatomy of the glenohumeral ligaments is useful in detecting pathology. These ligaments are variable in number and variable in size. Stability of the glenohumeral joint is based on multiple factors. Therefore glenohumeral ligament lesions are associated with coexisting structural abnormalities including capsule, labrum, rotator cuff, coracoacromial arch and bone. Magnetic resonance (MR) arthrography is the method of choice to visualize intraarticular pathology.
