Fig. 2From: Volume of the proximal half of the thoracic aorta is the most comprehensive FDG-PET/CT indicator of arterial aging throughout adulthoodRepresentative paired fused PET/CT and CT aorta plane slices of young, middle-aged, and older adults (3 individuals per age-group). The color scale legend for PET images is shown on the right. Aorta calcifications are only observed on CT slices of the older age-group. Note the changes in intensity and heterogeneity of aorta FDG activity and aorta volume with the aorta uncoiling with increasing ageBack to article page
