Cardiac magnetic resonance (CMR) can be utilized for non-invasive estimation of blood oxygen (O2) saturation in complex pediatric heart disease (i.e., single ventricle physiology) with good correlation to current gold standard catheter-derived measurements. Oximetry maps derived from T2 CMR data can enhance visualization of regional O2 saturations and may guide optimization of image acquisition and analysis.
