Oxygenation changes throughout the cardiac cycle as assessed by CMR during apnea in the blood (left) and the myocardium (right). While the signal intensity in the blood drops in the blood (de-oxygenation), it increases in the myocardium due to increased myocardial blood flow. Measurements were performed in the same images (modified from [23].
