Abstract: Background: The aim of the study was to investigate the metabolic activity of aneurysms
of the main arteries. It has been done in retrospective analysis of routine oncological 18FDG
PET-CT.
Materials and Methods: In our material (2 925 FDG PET/CT studies), aneurysms were found in
26 patients (8 F/18 M), 5 of whom had inflammatory aneurysms. The diameter of the aneurysm
was measured at its widest point, while the metabolic activity was determined by SUV max. No
significant correlation between the size of the aneurysm and its activity was found.
Results: When comparing inflammatory aneurysms to non-inflamed ones no significant differences
in maximum size were found.
Conclusion: However, notable differences in maximum activity were observed (p <0.01). There
were no relation between the size and metabolic activity of aneurysms.
