Heatmap of Correlations Between Tracer Uptake in Tissues of Interest

Heatmap showing correlations between tracer uptake in the infarct, spleen, and bone marrow. For ¹⁹F-MRI, in vivo TBRs were used. For the PET tracers, ex vivo gamma counting data were used. Colors represent Spearman’s r, and significant correlations are outlined by a blue line. For simplicity, inverse correlations were converted to positive values. See Supplemental Figure 6 for individual graphs.
