An ULD-CT and a non-contrast chest CT (NCCT) scan were then performed. Three radiologists assessed the sCXR and ULD-CT examinations for cardiogenic pulmonary edema, pneumonia, pneumothorax, and pleural effusion. Resources and effort were compared for sCXR and ULD-CT to evaluate feasibility. Diagnostic accuracy was calculated for sCXR and ULD-CT using NCCT as the reference standard.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean effective dose of ULD-CT was 0.05\u00b10.01 mSv. For pleural effusion and cardiogenic pulmonary edema, no difference in diagnostic accuracy between ULD-CT and sCXR was observed. For pneumonia and pneumothorax, sensitivities were 100% (95% confidence interval [CI] 69\u2013100) and 50% (95% CI 7\u201393) for ULD-CT and 60% (95% CI 26\u201388) and 0% (95% CI 0\u20130) for sCXR, respectively. Median examination time was 10 min for ULD-CT vs. 5 min for sCXR ( P&lt;0.001). For ULD-CT 1\u20132 more staff members were needed compared to sCXR ( P&lt;0.001). ULD-CT was rated more challenging to perform than sCXR ( P&lt;0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>ULD-CT seems equal or better in detecting acute chest conditions compared to sCXR.
