From: Utility of 18 F-FDG and 11C-PBR28 microPET for the assessment of rat aortic aneurysm inflammation
18 F-FDG autoradiography. Representative autoradiography (A, B, E, F), block face photographs (C, G) and fusion images (D, H) of a representative IPPE control (A-D) and an APPE AAA animal (E-H). (A and E) represent 18 F-FDG uptake (in PSL/mm2), while (B and F) are gray-scale images displayed with optimal contrast settings for fusion. The 18 F-FDG uptake in the aortic wall is increased in the APPE AAA wall (AMRARG 7.91 ± 1.97) compared to the IPPE control aortic wall (AMRARG 1.23 ± 0.52). The aortic wall (red arrows), blood pool (yellow arrows), and psoas musculature (black arrows) are identified (scale bar 5 mm).
