Fifty-six patients with musculoskeletal disorders involving the shoulder were examined using two-dimensional computed tomography multiplanar reconstruction and volumetric three-dimensional (3D) image processing. Two- and three-dimensional imaging of the shoulder demonstrated advantages over conventional radiography in clarifying areas of complex anatomy. The techniques were found most beneficial for (1) delineating complex fractures; (2) evaluating joint instability; (3) localizing foreign bodies; (4) detecting lytic lesions; (5) assessing soft tissue pathology; and (6) identifying causes for decreased range of motion. Two-dimensional multiplanar reconstruction provided superior views of the scapula and permitted a better understanding of the orientation of the glenoid. Multiplanar reconstruction displayed deep soft tissue anatomy more clearly, including the course of important neurovascular structures. Volumetric 3D imaging added several unique perspectives, providing a more comprehensive representation of the shoulder and its articulating surfaces. The ability to rotate the shoulder about he vertical and horizontal axes in an animated video loop and to edit away confusing, overlying structures provided a "real-time" 3D model of the shoulder for planning treatment.
对56例患有累及肩部的肌肉骨骼疾病的患者进行了二维计算机断层扫描多平面重建和容积三维（3D）图像处理检查。肩部的二维和三维成像在清晰显示复杂解剖区域方面显示出优于传统放射摄影的优势。这些技术被发现对以下方面最为有益：（1）描绘复杂骨折；（2）评估关节不稳定；（3）定位异物；（4）检测溶骨性病变；（5）评估软组织病理学；以及（6）确定活动范围减小的原因。二维多平面重建提供了肩胛骨的 superior views，并有助于更好地理解肩胛盂的方向。多平面重建更清晰地显示了深部软组织解剖结构，包括重要神经血管结构的走行。容积3D成像增加了几个独特的视角，提供了肩部及其关节面更全面的图像。能够在动画视频循环中围绕垂直和水平轴旋转肩部，并编辑掉令人困惑的重叠结构，为治疗规划提供了肩部的“实时”3D模型。
