CCR2 and triple-A syndrome: Although by week 2, AAA diameter was equivalent between groups, PET/CT with 64Cu-DOTA-ECL1i (selective CCR2-targeting PET radiotracer12,14,26) demonstrated significantly reduced CCR2 uptake in AAAs of KDp rats throughout study period (week 1, p = 0.05; week 2, p =  < 0.0001; Fig. 2G and H).
