Abstract
Because they distend the shoulder joint and bathe the labrum with contrast, CT arthrography (CTa) and MR arthrography (MRA) are both excellent tests for evaluating the labrum. In this article, we discuss the advantages and disadvantages of each examination. We also describe techniques for performing CTa and MRA, including how to maximize image quality. The normal anatomy of the labrum and glenohumeral ligaments is described and demonstrated on both CTa and MRA images. To improve communication with orthopedic surgeons, the discussion of the pathology and normal variants of the labroligamentous complex is organized by functional anatomic regions. CTa and MRA images are then used to demonstrate a variety of pathologic and normal variant appearances of the labroligamentous complex.
