Correlations of image-derived myocardial ¹⁸F-flurpiridaz uptake (%ID/g tissue) following regadenoson-induced stress, with tissue volume of distribution (V_T). Early time intervals revealed lower R² values, while later time intervals reached an R² value of up to 0.98, indicating an excellent correlation between V_T and %ID/g tissue ¹⁸F-flurpiridaz. Averaged time intervals included (A) 0-2 min, (B) 2-7 min, (C), 7-11 min, (D) 11-20 min, (E) 20-40 min and (F) 0-40 min post injection
