Figure 17b. Arthroscopically confirmed subluxated and partially torn long head of biceps brachii tendon (arrow) and partially torn subscapularis tendon. (a, b) Transverse T1-weighted MR arthrographic images (700/10) obtained with fat saturation after intraarticular administration of dilute gadolinium compound show long head of biceps brachii tendon is surrounded by contrast agent anterior to the superficial subscapularis tendon fibers (*), deep to the coracohumeral ligament (white arrowheads).
