Résumé
The current standard method to measure intracardiac oxygen (O 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 healthy subjects. T2-prepared single-shot balanced steady-state free-precession at 1.5T. MR signals in venous and arterial blood, hematocrit, and arterial O Coefficient of variation, intraclass correlation coefficient, Bland-Altman analysis, Pearson's correlation. The coefficient of variation for interstudy reproducibility of O MR oximetry is repeatable and reproducible. Good agreement was shown between MR and catheter venous O 2. 2.
