Accurate diagnosis is crucial for effective treatment and prevention. This case-based study assessed the use of computed tomography for diagnosing these diseases in sheep. Thirty-three sheep showing clinical signs of one or more upper respiratory tract diseases underwent computed tomography scans, which were compared to clinical diagnoses and postmortem examinations. Results showed that clinical diagnosis matched the postmortem findings in 26 of 38 cases, while computed tomography diagnosis matched in 36 of 38 diagnosed conditions, demonstrating higher accuracy. Computed tomography provided detailed anatomical reconstructions of the respiratory tract, allowing precise detection of lesions, identification of their origin or content, and clear visualisation of surrounding structures. Despite limitations such as high costs, risks related to general anaesthesia, and radiation exposure, its accuracy makes it a valuable tool for managing these diseases. The creation of extensive databases on common diseases affecting sheep could improve the accessibility and effectiveness of computed tomography in veterinary clinics. info:eu-repo/grantAgreement/ES/DGA/AR15-23R info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Quílez, Pablo Universidad de Zaragoza (orcid)0009-0003-9757-3840 Ortín, Aurora Universidad de Zaragoza (orcid)0000-0002-0313-5926 Villanueva-Saz, Sergio Universidad de Zaragoza (orcid)0000-0001-6209-4282 Ruiz de Arcaute, Marta Universidad de Zaragoza (orcid)0000-0002-7655-2472 Climent, María Universidad de Zaragoza (orcid)0000-0002-0606-0763 De las Heras, Marcelo Universidad de Zaragoza (orcid)0000-0003-3792-287X Ruiz, Héctor Universidad de Zaragoza (orcid)0000-0002-8474-2831 Navarro, Teresa Universidad de Zaragoza (orcid)0000-0002-4557-6033 Lacasta, Delia Universidad de Zaragoza (orcid)0000-0002-7822-6646 1001 025 Universidad de Zaragoza Dpto.
