Moris et al. discuss several emerging biomarkers impli-cated in the pathophysiology of abdominal aortic aneurysms (AAAs) [1]. These include biomarkers related to AAA extra-cellular matrix homeostasis or proteolysis, cellular or sig-nalling pathways, proteins released by intraluminal thrombi, circulating cells and inflammation,metabolomics and genetic biomarkers. One emerging biomarker which probably also deserves to be mentioned is 18F-fluorodeoxyglucose (18F-FDG). 18F-FDG uptake detected by positron emission tomogra-phy (PET) is used to assess hypermetabolic activity of cells in tumors and inflammatory processes [2, 3]. Inflammation plays a key role in the development of AAAs [4]. AA
