螺旋CT三维重建观察实验猕猴胸部大血管系统

Observation on Chest Big Vascular System of Rhesus Monkey by Three-dimensional Spiral CT Reconstruction

目的利用256层螺旋CT三维重建观察实验猕猴胸部大血管，为猕猴血管系统的研究、数字化猴的建立及科学研究提供资料。方法（1）选择实验猕猴10只，雌雄各半，年龄6～10岁，进行胸部CT断层扫描试验。（2）动物全身麻醉后，采用平扫及增强扫描技术，进行容积数据采集，获取正常猕猴胸部CT横断面影像。（3）利用CT图像后处理技术对扫描获得的容积数据进行三维的图像重组处理。结果获得了良好的主动脉、肺动静脉等胸部大血管三维重建的立体影像，本文展示了2幅三维重组图像。从比较解剖学的角度，观察到了猕猴胸部血管的结构特点及与人类的区别。结论CT三维重建能很好地反映了猕猴胸部血管系统的解剖结构、走行及与周围结构的位置关系，它是有效的、无创伤性的、直观的观察血管系统的理想方法。

Objective Observing rhesus monkey big vascular system of chest by 256 layer spiral CT and providing scientific materials for studying rhesus monkey vascular and digitization system. Methods Five male and five female rhesus monkeys aging at 6 to 10 years old were selected and obtained for CT scanning experiment. Rhesus monkey chest CT cross-sectional images were acquired through flat and strengthen scanning technique to collect volume data. Rhesus monkey volume data were processed by 3D image restruction using CT image post-processing technology. Results Rhesus monkey stereoscopic images of aorta, pulmonary artery and vein and chest big vascular were obtained by Three-dimensional reconstruction. From the point of comparative anatomy the difference of chest big vascular system between rhesus monkey and human being were found. Conclusion The anatomical and tissue structures of rhesus monkey among the big vascular system were reflected perfectly by Three-dimensional CT reconstruction. It is an effective, non-invasive and direct ideal way of observation of the vascular system,
