Fig. 3From: Peak flow measurements in patients with severe aortic stenosis: a prospective comparative study between cardiovascular magnetic resonance 2D and 4D flow and transthoracic echocardiographyA Aortic peak systolic flow velocity measured from 90 patients with transthoracic echocardiography (TTE), 2D flow, 2D flow with angle correction, and 4D flow measured by the commercially available method (4D flow) and the maximum intensity projection–based method described in [23] (4D flow MIP). P-values compared to TTE. B Peak flow velocity measured by 4D flow from 10 patients at the level of the highest flow, 2D flow measurement plane and the five anatomical planes.
