Figure 4

Correlation between stress MBF and dT1 during regadenoson stress. Stress MBF measured at ~ 4 (early stress) and ~ 15 min (late stress) after regadenoson in the same individuals on two separate days. Comparisons between dT1 and stress MBF are made for measured dT1 at the time point closest to MBF (all stress T1 data points measured within 90 s prior to MBF acquisition). Confidence intervals for the linear regressions are included (shaded ranges).
