Special Issue Information

Dear Colleagues,

The abdomen houses numerous essential organ systems, such as the hepatobiliary, pancreatic, gastrointestinal, and genitourinary systems, which are often impacted by a diverse range of conditions. Imaging plays a crucial role in the diagnostic process, which can be particularly challenging due to the complexity of the anatomy and the diverse pathology that can occur. It is also essential for staging, treatment planning, and monitoring therapeutic response.

Advancements in imaging technologies, including state-of-the-art modalities and sophisticated post-processing techniques, continue to enhance diagnostic accuracy but also demand a high level of expertise from interpreting clinicians. Furthermore, the integration of artificial intelligence into abdominal imaging is revolutionizing the field, promising new insights and improved prognostication for patients.

This Special Issue aims to highlight the latest developments and innovations in abdominal imaging for small animals. We welcome original research and comprehensive reviews addressing conventional imaging, advanced modalities, cutting-edge post-processing techniques, artificial intelligence applications, and their impact on diagnosis and clinical outcomes.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: articles, reviews, communication, commentary, and case reports.

I look forward to receiving your contributions.

Dr. Agustina Ansón
Guest Editor

Abstract
Imaging is commonly used to help diagnose pancreatic disease in cats. In order to establish normal computed tomography (CT) measurements for the pancreatic ducts in cats, images of 78 cats without clinical evidence of pancreatic disease, and with normal DGGR (1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6′-methylresorufin) ester [...] Read more.
Imaging is commonly used to help diagnose pancreatic disease in cats. In order to establish normal computed tomography (CT) measurements for the pancreatic ducts in cats, images of 78 cats without clinical evidence of pancreatic disease, and with normal DGGR (1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6′-methylresorufin) ester lipase values, were evaluated retrospectively by two reviewers. The left pancreatic duct measured 1.4 ± 0.8 mm (mean ± standard deviation), the right pancreatic duct measured 1.1 ± 0.5 mm, and the common duct measured 1.6 ± 0.8 mm. All ducts were better visualised post-contrast, with the left pancreatic duct identified most frequently (not visualised on post-contrast images in only 3% of cases). There was visibility of the right and common hepatic ducts less frequently, not observed post-contrast in 22 and 20% of cases, respectively. The duodenal papilla measured 2.8 ± 0.7 mm in diameter. It had an HU of 43 ± 14 pre-contrast and 109 ± 32 post-contrast. It was identified in all but 6% of cases on post-contrast images. This study shows that the pancreatic ducts and duodenal papilla can be seen on post-contrast images and provides normal ranges of size for the pancreatic duct and duodenal papilla. Full article
