From: Probing myocardial blood oxygenation reserve with controlled hypercapnia using BOLD CMR
BOLD CMR-based evaluation of adenosine versus hypercapnia in the presence of LAD stenosis in canines. Representative color-overlaid BOLD CMR images acquired during adenosine infusion, hypercapnia, and rest from a canine with a significant narrowing of LAD. Color bar shows BOLD CMR signal intensity. Images acquired under adenosine infusion and at rest were obtained under normocapnia.
