From: Oxygenation-sensitive CMR for assessing vasodilator-induced changes of myocardial oxygenation
Examples of BOLD-CMR images a) at baseline; c) during infusion of 0.3 mg/min adenosine (Ade 3). The perfusion territory of the LCX after intracoronary injection of gadopentetate dimeglumine is shown in b) (arrows). Panel d) shows the myocardial signal intensity of baseline subtracted from that during adenosine. The higher values in the LCX territory reflect the signal intensity increase during in the LCX perfusion territory as induced by adenosine injection.
