This position statement outlines the guiding principles for the ethical development and integration of AI technologies to ensure patient safety and clinical effectiveness. Artificial intelligence systems must adhere to good machine learning practices, emphasizing transparency, error reporting, and the involvement of clinical experts throughout development. These tools should also include robust mechanisms for secure patient data handling and postimplementation monitoring. The position highlights the critical importance of maintaining a veterinarian in the loop, preferably a board-certified radiologist or radiation oncologist, to interpret AI outputs and safeguard diagnostic quality. Currently, no commercially available AI products for veterinary diagnostic imaging meet the required standards for transparency, validation, or safety. The ACVR and ECVDI advocate for rigorous peer-reviewed research, unbiased third-party evaluations, and interdisciplinary collaboration to establish evidence-based benchmarks for AI applications. Additionally, the statement calls for enhanced education on AI for veterinary professionals, from foundational training in curricula to continuing education for practitioners. Veterinarians are encouraged to disclose AI usage to pet owners and provide alternative diagnostic options as needed. Regulatory bodies should establish guidelines to prevent misuse and protect the profession and patients. The ACVR and ECVDI stress the need for a cautious, informed approach to AI adoption, ensuring these technologies augment, rather than compromise, veterinary care.</p>","PeriodicalId":14658,"journal":{"name":"Javma-journal of The American Veterinary Medical Association","volume":" ","pages":"1-4"},"PeriodicalIF":1.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the current review was to provide a practical overview of the current literature of and, in some cases, the authors' experience in the diagnosis and management of gallbladder mucocele formation in dogs. Key takeaways were that gallbladder mucocele formation is caused by secretion of abnormal mucus by the gallbladder epithelium and has a predilection for older, small-sized purebred dogs. These dogs are often concurrently diagnosed with hypothyroidism, hyperadrenocorticism, hyperlipidemia, and proteinuria. Diagnosis is reliant on ultrasonographic features demonstrating the presence of non-gravity-dependent mucus that is adherent to the walls of the gallbladder and encroaching into the lumen. The definitive treatment for mucocele formation is cholecystectomy, which carries a significant short-term mortality but good long-term prognosis.</p>","PeriodicalId":14658,"journal":{"name":"Javma-journal of The American Veterinary Medical Association","volume":" ","pages":"1-9"},"PeriodicalIF":1.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These quantitative assays offer several advantages compared to classical serological assays, like a lower limit of detection, less background, and a broader linear quantification range, all of which improve test accuracy. The simultaneous multiplex analysis of a patient's serological response to several specific antigens also improves the diagnostic result interpretation. This influences treatment and management decisions and often allows for a quantitative follow-up as treatment response evaluation. In this review article, we discuss examples of 3 diagnostic multiplex assays for antibody detection in veterinary patients: the Lyme Multiplex assay, the Canine Brucella Multiplex assay, and the Equine Herpesvirus Type-1 Risk Evaluation assay. In addition, multiplex assays for immune response markers, like soluble cytokines, chemokines, or other inflammatory proteins, have recently become available. Currently, these assays are mainly used as clinical research tools to broadly evaluate immune activation and/or inflammation during a variety of infectious and noninfectious diseases.
