Conventional radiographs, axial CT with multiplanar 2-D and 3-D-CT reformations were obtained in 20 patients presenting with craniofacial injuries, to evaluate the capabilities of 3-D-CT. The image quality was assessed by two readers. Sagittal and oblique components as well as comminuted fractures could be detected by 3-D-CT reconstructions similarly to axial CT with 2-D reformations. Displacements over 2 mm were confidently documented by 3-D-CT images. 3-D-CT reconstructions allow an improved demonstration of rotational components of fractured fragments. 3-D-CT images are not as accurate as 2-D-CT in the primary detection of fractures in the relevant anatomic regions. Among 3-D-CT reconstructions, the lateral and partly the facial regions are adequately visualised.
对20例颅面部损伤患者进行了常规X线摄影、具有多平面二维和三维CT重建的轴向CT检查，以评估三维CT的性能。由两名阅片者评估图像质量。三维CT重建能够检测矢状和斜行骨折以及粉碎性骨折，与二维重建的轴向CT类似。三维CT图像能够可靠地记录超过2mm的移位。三维CT重建能更好地显示骨折碎片的旋转情况。在相关解剖区域骨折的初步检测中，三维CT图像不如二维CT准确。在三维CT重建中，外侧及部分面部区域显示良好。
