In MR imaging of the shoulder, diagnostic success requires the delineation of complex anatomic structures and the demonstration of subtle abnormalities. Magnetic resonance (MR) arthrography extends the capabilities of conventional MR imaging because contrast solution separates intra-articular structures and outlines abnormalities. There are several major contributions of MR arthrography. In assessment of the rotator cuff, arthrographic MR images enable the accurate differentiation of full-thickness tears from other cuff abnormalities, as well as the determination of tendon quality. In shoulders with suspected glenohumeral instability, arthrographic MR images show the locations of labral tears relative to the origins of glenohumeral ligaments. This article illustrates normal arthrographic MR features of the shoulder as well as common pathological disorders of the rotator cuff and labral-ligamentous complex.
在肩部的磁共振成像中，诊断成功需要清晰显示复杂的解剖结构并发现细微异常。磁共振关节造影扩展了传统磁共振成像的功能，因为对比剂可分离关节内结构并勾勒出异常情况。磁共振关节造影有几个主要作用。在评估肩袖时，关节造影磁共振图像能够准确区分全层撕裂与其他肩袖异常，还能确定肌腱质量。在怀疑存在盂肱关节不稳的肩部，关节造影磁共振图像可显示盂唇撕裂相对于盂肱韧带起点的位置。本文阐述了肩部正常的关节造影磁共振特征以及肩袖和盂唇 - 韧带复合体常见的病理紊乱情况。
