Time course of 18 F-FDG and 11C-PBR28 AMR
. The 18 F-FDG AMRPET (mean ± SEM) of APPE (black circles, black lines) of AAA animals at day 14 was significantly greater than that at day 3 (p = 0.03) and day 7 (p = 0.002); whereas the 18 F-FDG AMRPET of IPPE control animals (white circles, dashed lines) decreased over the 14-day period (p = 0.01 day 3 vs. day 14). APPE AAA animals also demonstrated a significantly greater 18 F-FDG AMRPET at day 14 compared to IPPE controls (p = 0.0002). At day 14, the 11C-PBR28 AMRPET was significantly greater (p = 0.04) in APPE (black triangles) compared to IPPE controls (white triangles).
