Comparison of PVRi calculated with the Fick principle and with CMR flow at baseline on room air.

a Correlation between PVRi calculated with the Fick principle and with CMR flow at baseline on room air (n = 54 paired calculations). b Bland-Altman plot of the difference in PVRi calculated with the two methods, and mean PVRi with the two methods. PVRi: pulmonary vascular resistance index
