Few instances of neoplastic formations in the liver of chinchillas have been found, even though the species is widely used in different scientific experiments. In the present article we investigate the anatomical features of the chinchilla's liver using CT and three dimension (3D) imaging. For the trials we used 12 (six males and six females) clinically healthy chinchillas all at 18 months of age. The animals were positioned in dorsal recumbency. We used Th8 to L2 vertebrae and the sternum as bone markers for the transverse CT study. The investigated anatomical landmarks for the CT coronal study were the vertebrae, costal arch, soft abdominal wall, diaphragm, stomach and the right kidney. 3D reconstructions were accomplished with a specific imaging software. On transverse and coronal CT images, the chinchilla's liver was composed of lobus hepatis sinister lateralis, 'middle lobe'-without proper Latin term in NAV 2017, lobus hepatis dexter and lobus caudatus. The 'middle lobe' was separated into the 'left middle lobe' and the 'right middle lobe'. Lobus hepatis dexter consisted of lobus hepatis dexter medialis and lobus hepatis dexter lateralis. There was an anatomical relation between the liver, fundus ventriculi and corpus ventriculi. Proc. caudatus was in close contact with the right kidney. Vesica fellea was elongated and ellipsoid. 3D reformatted images confirmed the results obtained by transverse and coronal CT studies. The CT density of the liver in HU was 195.6 ± 73.1. The CT and 3D reconstructed images were visualized at high resolution. This data could be used as a basis for further morphological and imaging studies.
在对广泛应用于不同科学实验的龙猫进行研究时，仅发现少数肝脏肿瘤病例。在本文中，我们使用 CT 和三维（3D）成像技术研究龙猫肝脏的解剖结构。试验共使用 12 只（6 只雄性，6 只雌性）18 月龄、临床健康的龙猫。动物采取俯卧位。我们使用 Th8 到 L2 椎骨和胸骨作为横向 CT 研究的骨骼标志。用于 CT 冠状研究的解剖标志为椎体、肋弓、软腹壁、膈肌、胃和右肾。使用特定的成像软件进行 3D 重建。在横断和冠状 CT 图像上，龙猫肝脏由左外侧叶、无特定拉丁语名称的“中间叶”-2017 年 NAV、右叶和尾叶组成。“中间叶”分为“左中间叶”和“右中间叶”。右叶由右内侧叶和右外侧叶组成。肝脏、胃底和胃体之间存在解剖关系。尾突与右肾紧密相邻。胆囊拉长呈椭圆形。3D 重建图像证实了横断和冠状 CT 研究的结果。HU 肝 CT 密度为 195.6±73.1。CT 和 3D 重建图像可实现高分辨率可视化。这些数据可作为进一步形态学和影像学研究的基础。
