Fig. 5From: Quantification of aortic stenosis diagnostic parameters: comparison of fast 3 direction and 1 direction phase contrast CMR and transthoracic echocardiographyBland-Altman plot of comparison between 3Dir PC-CMR peak velocities derived from all three velocity components (3Dir PC-CMR speed) and the through-plane component (Z). Differences arise primarily from the 1/3 of the cases where speed was slightly higher than the unidirectional computed peak velocityBack to article page
