✦ Synopsis

BOLD-CMR was used to assess changes in myocardial oxygenation after volunteers performed controlled hyperventilation or breath holding. Signal intensity after hyperventilation decreased whereas an increase occurred after a breath hold demonstrating that controlled breathing techniques could alter myocardial oxygenation and be identified by BOLD-CMR in healthy volunteers.

## Abstract ## Background As myocardial oxygenation may serve as a marker for ischemia and microvascular dysfunction, it could be clinically useful to have a non-invasive measure of changes in myocardial oxygenation. However, the impact of induced blood flow changes on oxygenation is not well unde
