Understanding complex acetabular fractures is difficult and may require three-dimensional reformatted computed tomographic (CT) images. This paper evaluates a technique, digital rotational imaging (DRI), that displays multiple oblique images of the pelvis and acetabulum. When viewed statically, DRI provides optimal iliac and obturator oblique projections, often differing in obliquity from the conventional 45-degree orthogonal views. Dynamic DRI viewing in rapid sequence provides a three-dimensional effect that improves perception of acetabular fracture relationships.
理解复杂的髋臼骨折颇具难度，可能需要三维重建的计算机断层扫描（CT）图像。本文评估了一种名为数字旋转成像（DRI）的技术，该技术可显示骨盆和髋臼的多个斜位图像。静态观察时，DRI能提供最佳的髂骨和闭孔斜位投影，其倾斜度往往与传统的45度正交视图不同。快速连续动态观察DRI可产生三维效果，有助于增强对髋臼骨折关系的理解。
