The purpose of this study was to assess the feasibility of cone beam computed tomography (CBCT) in imaging dogs and cats for diagnostic dental veterinary applications. CBCT scans of heads of six dogs and two cats were made. Dental panoramic and multi-planar reformatted (MPR) para-sagittal reconstructions were created using specialized software. Image quality and visibility of anatomical landmarks were subjectively assessed by two observers. Good image quality was obtained for the MPR para-sagittal reconstructions through multiple teeth. The image quality of the panoramic reconstructions of dogs was moderate while the panoramic reconstructions of cats were poor since the images were associated with an increased noise level. Segmental panoramic reconstructions of the mouth seem to be useful for studying the dental anatomy especially in dogs. The results of this study using human dental CBCT technology demonstrate the potential of this scanning technology in veterinary medicine. Unfortunately, the moderate image quality obtained with the CBCT technique reported here seems to be inferior to the diagnostic image quality obtained from 2-dimensional dental radiographs. Further research is required to optimize scanning and reconstruction protocols for veterinary applications.
本研究的目的是评估锥形束计算机断层扫描（CBCT）在犬猫牙科诊断兽医应用成像中的可行性。对六只犬和两只猫的头部进行了CBCT扫描。使用专门软件创建了牙科全景和多平面重组（MPR）矢状旁重建图像。由两名观察者主观评估图像质量和解剖标志的可见性。通过多颗牙齿获得了MPR矢状旁重建的良好图像质量。犬的全景重建图像质量中等，而猫的全景重建图像质量较差，因为图像噪声水平较高。口腔的分段全景重建似乎对研究牙齿解剖结构有用，尤其是在犬类中。本研究使用人类牙科CBCT技术的结果证明了这种扫描技术在兽医学中的潜力。不幸的是，此处报告的CBCT技术获得的中等图像质量似乎不如二维牙科X光片获得的诊断图像质量。需要进一步研究以优化兽医应用的扫描和重建方案。
