Correlation of metabolic activity in the amygdala with various target tissues: Aorta, bone marrow, spleen, and skeletal muscle control (n = 45). Panel (a) FDG uptake in the amygdala positively correlated with FDG uptake in the aorta (r = 0.757). Panel (b) FDG uptake in the amygdala positively correlated with FDG uptake in the bone marrow (r = 0.750). Panel (c) FDG uptake in the amygdala positively correlated with FDG uptake in the spleen (r = 0.655). Panel (d) FDG uptake in the amygdala was not positively correlated, and in fact was weakly negatively correlated with FDG uptake in the skeletal muscle control. FDG, ¹⁸F‐fluorodeoxyglucose; SUV_max, standardized uptake value.
