18F-FDG PET scanning of abdominal aortic aneurysms and correlation with molecular characteristics: a systematic review

Table 2 Main findings of the systematic review

Finding	Reference
Increased FDG in AAA compared to controls	[13–15]
No difference or decreased FDG uptake in AAA compared to controls	[16–19]
Symptoms cause increased FDG uptake	[14]
Inflammatory AAAs have increased FDG uptake	[20]
FDG uptake correlates with pathological weakening of the aortic wall	[14, 25, 26, 29]
No correlation between FDG uptake and recent AAA growth	[14, 20]
Inverse correlation between FDG uptake and future expansion	[22, 23]
Inverse correlation between FDG uptake and aortic wall calcification	[16]
Positive association between FDG uptake and future AAA expansion or rupture	[11, 12, 21]
