Table 2 Main findings of the systematic review

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

Finding Reference
Increased FDG in AAA compared to controls [1315]
No difference or decreased FDG uptake in AAA compared to controls [1619]
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]
