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., (© 2024 Wiley-VCH GmbH.

AIM: To determine some macromorphological characteristics of the normal liver in rabbits. MATERIALS: We studied 12 mature, clinically healthy, euthanized rabbits, 8 months of age from New Zealand White breed and weighed between 2.8kg and 3.2kg. METHODS: Following laparotomy and extirpation of the rabbit liver we studied its topography and linear parameters. The results were collected and recorded. The obtained data was processed via variable statistical methods. RESULTS: The rabbit liver was situated in the epigastric region, between both costal arches. The caudate process touched the right kidney. The rabbit liver was caudally situated to the diaphragm and extended to the left and right abdominal walls. The left medial and lateral hepatic lobes were parallel to the right one. The quadrate lobe was too small. The gall bladder was cylindrical and didn't reach the ventral edge of the organ. The morphometric investigation showed that the left hepatic lobe was longer and bigger than the right one. The smallest structure in length and height was quadrate lobe. The gall bladder's three parts were with different sizes. CONCLUSION: The rabbit liver was lobated organ, composed of five lobes. The left hepatic lobe with its medial and lateral parts is with the biggest extent in the organ, while the quadrate lobe is the smallest. [ABSTRACT FROM AUTHOR]

Aim: Comparing results from rabbit liver's ultrasonographic, computed tomographic and anatomical topgraphic studies. Object: Nine healthy New Zealand white rabbits, aged 8 months, weighed 2.8 to 3.2 kg were studied. In the ultrasonographic investigation the animals were positioned in supine recumbency. The approach was transabdominal percutaneous hypochondrial. The abdominal cavity was transversally and sagittaly scanned by axial computer tomograph. The animals were positioned in supine recumbency. In the native anatomical investigation topographic rabbit liver's features were compared with its imaging anatomical findings. Results: The liver echogenicity was heterogeneous and lower than the close soft tissue strucrures. The gall bladder's wall was a hypoechoic finding.Cystic duct was observed in its beginning part. In the computed tomographic study, the liver was a massive, heterogeneous, normodense soft tissue finding. There wasn't visible border between lateral and medial left hepatic lobe and right hepatic lobe. In the native anatomical study the left and right hepatic lobes, quadrate lobe and gall bladder's parts were found. Conclusion: The comparative analysis of rabbit liver's imaging anatomical and native transversal study could be applied in the interpretation and diagnosis of many rabbit liver diseases.
