The scans were conducted at the Radiology Unit of the Foundation IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico of Milan and the Radiology Department of Treviglio-Caravaggio Hospital-ASST Bergamo Ovest. The study focused on optimizing patient selection and radiological recommendations to align with evidence-based guidelines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>This retrospective study included 280 patients (mean age 61.68\u00a0years; 51.07% women, 48.93% men) who underwent their first chest CT scan without contrast. Diagnostic outcomes were analyzed across different clinical queries. Incidental findings and radiologists\u2019 recommendations were assessed for alignment with Fleischner Society and ACR guidelines. Deviations were categorized as unnecessary imaging suggestions or missed indications. Radiation exposure was quantified using the dose-length product (DLP).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Diagnostic outcomes were positive in 54.64% of cases. Incidental findings occurred in 34.64% of cases, with guideline adherence at 81.43%. Deviations included unnecessary imaging in 14.29% and missed follow-up indications in 4.28% of cases.
