PBF ratios for ROIapical, ROImiddleand ROIcaudal. Maximum standardized uptake value (SUVmax) ratio for the apical, middle, and caudal ROIs, expressed as the median of the quotients of SUVmax left/right side in the control group (n = 6) and the median of the quotients of SUVmax injured/uninjured side in the injury group (n = 5). The data are shown as the median [25th and 75th percentiles] and the minimum to maximum values. A PBF quotient < 1 was determined based on lower concentrations of Ga-68 microspheres in the injured lung. P compared with the control group.
