The correlation of macrophage areas and FDG uptake. Linear regression analyses showing the correlation of macrophage areas and FDG uptake in the segments (n = 72) of descending thoracic aorta of the rabbits, expressed as concentration (μCi/ml) (A) (r = 0.48, p < 0.0001) and ratio of aortic uptake-to-blood activity (B) (r = 0.80, p < 0.0001).
