From: Quantifying sodium [18F]fluoride uptake in abdominal aortic aneurysms
Radiotracer uptake in different regions of the aorta. Mean tissue-to-background ratio (red) and aortic microcalcification activity (blue) in the regions of the abdominal aorta and the thoracic aorta. AMA, aortic microcalcification activity; TBR, tissue-to-background ratio. * = p < 0.05, *** = p < 0.001, **** = p < 0.0001
