CT-imaging-based anatomical and three-dimensional modeling of the head and neck arterial vessels of the miniature pig

目的利用血管铸型标本和CT重建三维模型技术探讨小型猪头颈部血管的解剖结构及其应用。方法制作一例小型猪头颈部血管铸型标本,通过128层螺旋CT扫描铸型标本,并重建小型猪头颈部血管的三维模型。结果铸型标本清晰显示小型猪头颈部血管的分布及其走行特点,其三维数字化模型逼真、立体感强,能从多角度、多层面地显示小型猪头颈部血管的走行及分布吻合情况。结论采用铸型标本和三维数字化模型相结合的方式对小型猪头颈部血管的分布及走行特点进行了探究,为建立猪脑血管模型从实体标本与虚拟化模型两方面提供了形态学的参考依据。

Objective To investigate the anatomical structure of arterial vessels in the head and neck of miniature pigs and the related application of vascular cast specimens,and the technology of three-dimensional model reconstruction by CT imaging. Methods A vascular cast specimen of a miniature pig head and neck was made by a 128-slice spiral CT scanning,and a three-dimensional model of the arterial vessels in the head and neck of the miniature pig was reconstructed.Results The cast specimen clearly showed the distribution and running characteristics of the arteries in the head and neck of a miniature pig. The three-dimensional digital model was realistic and stereoscopic,showing the running and distribution of arteries from multiple angles and layers. Conclusions The distribution and running characteristics of arterial vessels in the head and neck of a miniature pig have been investigated by the combination of cast specimen and three-dimensional digital model,providing a morphological reference for the establishment of pig cerebrovascular models in respects of both solid specimen and virtualized model.
