Initially, the AI was deployed in the background to confirm successful technical deployment, with AI findings not made available to radiologists, followed by full launch where all radiologists were provided access to AI findings and the tool was adopted as standard practice. Deidentified details of reporting radiologist, study ID, AI findings, AI access per case, series count and system reporting timestamps were retrospectively collected across both periods for all standalone NCCTB reported between Feb 2022 and Jan 2023.<\/p>\n<p class=\"p2\">Reporting time was defined as the time between the \u201cimage-opened\u201d and \u201cdictation-end\u201d timestamps. Data analysis was restricted to studies reported by radiologists whom reported a minimum of 50 studies with and without AI assistance. A linear mixed effects model was performed with reporting clinician as a random effect and reporting time as dependent variable, with a logtransform applied to estimate percent change in independent fixed variables. Time of day (in or out of hours), number of priority findings, worklist triage (critical, urgent or routine), series count and whether AI predictions were accessed, were evaluated as fixed effects.<\/p>\n<\/div>                            <\/div>\n                        <\/div>\n                                            <div class=\"study__row\">\n                            <div class=\"study__left\" data-aos=\"fade-up\">\n                                <h2 class=\"h5\">Results<\/h2>\n                            <\/div>\n                            <div class=\"study__right\" data-aos=\"fade-up\">\n                                <div class=\"text b1\"><p>A total of 18,550 studies reported by 30 radiologists were included in the analysis.
