Patient‐Adaptive Magnetic Resonance Oximetry: Comparison With Invasive Catheter Measurement of Blood Oxygen Saturation in Patients With Cardiovascular Disease

The current standard method to measure intracardiac oxygen (O2 ) saturation is by invasive catheterization. Accurate noninvasive blood O2 saturation by MRI could potentially reduce the duration and risk of invasive diagnostic procedures.To noninvasively determine blood oxygen saturation in the heart with MRI and compare the accuracy with catheter measurements.Prospective.Thirty-two patients referred for right heart catheterization (RHC) and five...
