We investigated whether static <sup>18</sup>F-FDG PET/CT and analysis of SUV or standardized uptake ratios (SUR<sub>stat</sub>, uptake time-corrected ratio of <sup>18</sup>F-FDG concentration in lung tissue and blood plasma) might be an alternative to dynamic <sup>18</sup>F-FDG PET/CT and Patlak analysis for quantification of pulmonary inflammation in experimental ARDS.
