From: Oxygenation-sensitive CMR for assessing vasodilator-induced changes of myocardial oxygenation
Linear correlation of SvO 2 changes from baseline values versus myocardial BOLD-CMR signal intensity relative to baseline (n = 6). Regression lines (dashed lines) are shown. Baseline, adenosine and acetylcholine induced changes in flow represented as circles, squares and triangles, respectively. Figure 4 includes the results of the analyses of extrapolated lines.
