To describe the anatomic features of dentition and surrounding structures of the head in rabbits assessed by use of a newly developed micro-computed tomography (CT) device.
Cadavers of 7 clinically normal adult Dendermonde White domestic rabbits raised for human consumption.
The rabbits were slaughtered in a slaughterhouse, flayed, and decapitated; the rabbit heads were frozen for micro-CT examination. Transverse images were obtained from the nares to the occipital condyles with a custom-designed micro-CT scanner built at the Ghent University Centre for X-ray Tomography. Scan settings were chosen to highlight bony structures on the basis of the designers' experience. The micro-CT images were reviewed, and all recognizable anatomic features were labeled. Afterward, micro-CT images were used to create 3-D reconstructions by use of a custom-developed reconstruction package and 3-D rendering with dedicated software.
Microstructures of the bones and teeth were clearly visible on micro-CT images. Conversely, soft tissue contrast was relatively poor on these images.
Micro-CT appeared to be a promising technique for appropriate diagnosis of dental disease in rabbits. Further research is needed to determine the clinical applications of micro-CT imaging.
描述使用新开发的微型计算机断层扫描（CT）设备评估的兔牙列及头部周围结构的解剖特征。
7只供人类食用的临床正常成年登德蒙德白家兔的尸体。
兔在屠宰场被宰杀、剥皮并斩首；兔头冷冻后进行微型CT检查。使用根特大学X射线断层扫描中心制造的定制微型CT扫描仪从鼻孔至枕髁获取横向图像。根据设计者的经验选择扫描设置以突出显示骨质结构。对微型CT图像进行检查，并标记所有可识别的解剖特征。之后，使用定制开发的重建软件包和专用软件进行三维渲染，利用微型CT图像创建三维重建图像。
微型CT图像上骨骼和牙齿的微观结构清晰可见。相反，这些图像上的软组织对比度相对较差。
微型CT似乎是一种用于兔牙病正确诊断的有前景的技术。需要进一步研究以确定微型CT成像的临床应用。
