Fig. 2From: The impact of hematocrit on oxygenation-sensitive cardiovascular magnetic resonanceDifferences in signal intensity changes between hydration states. DICOM subtraction images demonstrate that hemodilution increases the OS signal at rest (a). Furthermore, the breathing maneuver could significantly induce a transient increase in myocardial oxygenation in normal conditions (b), but this response was attenuated in a hemodiluted state (c)Back to article page
