Figure 2From: Oxygenation-sensitive cardiovascular magnetic resonanceCorrelation of changes of myocardial oxygenation during Adenosine infusion with blood flow and coronary sinus oxygenation. Note the exponential relationship between flow and signal intensity as opposed to the linear relationship with changes of coronary sinus blood oxygenation, showing that signal intensity changes reflect changes of oxygen and not blood flow (modified from [19].Back to article page
