UNLABELLED: The characterization of pulmonary nodules (PN) is a primary indication for [ OBJECTIVE: Our objective was to compare the diagnostic efficacy of [ METHODS: We prospectively analyzed 51 patients to assess PN using [ RESULTS: A total of 84 PN were evaluated, comparing those in DIBH versus free-breathing, finding statistically significant differences in SUVmax values P(<
0.05) (mean SUVmax 3.7 in free-breathing vs. 5.33 in DIBH). When analyzed by location in lobes, we did not find statistically significant differences, though there was a trend towards higher SUVmax values in the lower lobes. [ CONCLUSIONS: The acquisition of [
