To obtain a detailed anatomic description of the rabbit head by means of computed tomography (CT).
6 clinically normal Dendermonde White rabbits weighing 3 kg and raised for human consumption and 1 Netherland dwarf rabbit.
The commercially raised rabbits were slaughtered in a slaughterhouse, flayed, and decapitated. The dwarf rabbit was euthanatized. Two hours later, each rabbit head was positioned with the ventral side on the CT table to obtain transverse and sagittal, 1-mm-thick slices. Dorsal images were obtained by placing each head perpendicular to the table. Immediately after the CT examination, 3 heads were frozen in an ice cube at -14 degrees C until solid and then sectioned at 4-mm-thick intervals by use of an electric band saw. Slab sections were immediately cleaned, photographed, and compared with corresponding CT images. Anatomic sections were examined, and identified anatomic structures were matched with structures on corresponding CT images.
The bone-window CT images yielded good anatomic detail of the dentition and the bony structures of rabbit skulls. The soft tissue structures that could be determined were not better identifiable on the soft tissue-window CT images than on the bone-window images.
CT images of the heads of healthy rabbits yielded detailed information on the skull and some surrounding soft tissue structures. Results of this study could be used as a guide for evaluation of CT images of rabbits with various cranial and dental disorders.
通过计算机断层扫描（CT）获得兔头部的详细解剖描述。
6只临床正常的登德蒙德白兔，体重3千克，为供人类食用而饲养，以及1只荷兰侏儒兔。
商业饲养的兔子在屠宰场宰杀、剥皮并斩首。侏儒兔实施安乐死。两小时后，将每个兔头腹侧朝下放置在CT检查台上，以获取1毫米厚的横断和矢状切片。通过将每个兔头垂直于检查台来获取背侧图像。CT检查后，立即将3个兔头置于-14摄氏度的冰块中冷冻至固体，然后用电锯以4毫米的间隔切片。切片立即清洗、拍照，并与相应的CT图像进行比较。检查解剖切片，并将识别出的解剖结构与相应CT图像上的结构进行匹配。
骨窗CT图像提供了兔颅骨牙列和骨结构的良好解剖细节。在软组织窗CT图像上可确定的软组织结构并不比骨窗图像上更容易识别。
健康兔头部的CT图像提供了有关颅骨和一些周围软组织结构的详细信息。本研究结果可作为评估患有各种颅骨和牙齿疾病的兔的CT图像的指南。
