Chronic pancreatitis(CP)is a complex condition marked by persistent inflammation,fibrosis,irreversible damage to the pancreatic parenchyma,and the eventual onset of exocrine or endocrine dysfunction.Effective treatment critically depends on early diagnosis.Utilizing imaging technology,which provides a noninvasive approach to assess both morphological and functional changes in the pancreas,holds great promise in the timely detection of CP.Despite the high incidence of CP in dogs and cats,along with their extensive use as animal models for studying the pathogenesis and diagnostic methods of this condition,the application of imaging technology for diagnosing chronic pancreatitis in these animals has fallen short,leading to continued challenges in CP diagnosis and evaluation.Notably,there is currently a lack of systematic description of imaging diagnostic methods for pancreatitis across different species.Consequently,the aim of this article is to critically evaluate and present the advancements in research regarding imaging diagnostic methods for chronic pancreatitis in humans,dogs,and cats.
