Radiometabolites of glycogen metabolism and the oxPPP correlate with total radioactivity in tissues and with each other

(A) Spearman correlation between the levels of 2-[¹⁸F]FDG-1-P, 2-[¹⁸F]FD-PGL/PG1, 2-[¹⁸F]FDG/2-[¹⁸F]FDM (unphosphorylated pool) and percent injected dose per gram (% ID/g) tissue.

(B) Heatmap of correlations between radiometabolites (n = 9–21). Asterisks report statistical significance: ∗p ≤ 0.05, ∗∗p ≤ 0.01, ∗∗∗p ≤ 0.001, ∗∗∗∗p ≤ 0.0001; the correct nomenclature has been omitted in (B).
