Figure 4From: Utility of 18 F-FDG and 11C-PBR28 microPET for the assessment of rat aortic aneurysm inflammation11C-PBR28 time-activity curves. About 10 min after radiotracer injection, the aorta-to-muscle background ratio (AMRPET) for 11C-PBR28 was fairly stable and consistently higher in APPE AAAs (black triangles) compared to IPPE control aortas (white triangles). APPE and IPPE data points are separated (in time) for clarity.Back to article page
