The shoulders of six normal volunteers were imaged with high-resolution MR in the axial, sagittal, and coronal planes. An angled pair of counter-rotating current loop-gap resonators designed specifically for the shoulder was used as a local coil. All images were compared with corresponding cryomicrotome sections from cadaver shoulders. The rotator cuff was analyzed in detail. It appeared as a complex, heterogeneous band to tissue superficial to the humeral head. The areas of low signal intensity corresponded to the central tendons of the four rotator cuff muscles. These tendons could be distinguished from each other as well as from the intervening components of the cuff, which have a moderate intensity. We concluded that MR is capable of imaging the normal rotator cuff and of separating the various components. This may allow for improved precision in the diagnosis of rotator cuff disorders.
对六名正常志愿者的肩部进行了轴向、矢状面和冠状面的高分辨率磁共振成像。使用专门为肩部设计的一对成角度的反向旋转电流环隙谐振器作为局部线圈。所有图像均与来自尸体肩部的相应冷冻切片进行比较。对肩袖进行了详细分析。它在肱骨头表面的组织中表现为一条复杂的、异质性的带。低信号强度区域对应于四块肩袖肌肉的中央肌腱。这些肌腱彼此之间以及与肩袖的中间成分(其信号强度中等)都可以区分开来。我们得出结论,磁共振成像能够对正常肩袖进行成像,并区分其各个组成部分。这可能会提高肩袖疾病诊断的准确性。
