Fig. 3
Representative 3Dir PC-CMR images in a patient with mild aortic stenosis (Vpeak = 2.75 m/s) using ReVEAL-based image recovery (see also Additional file 2). (a) The minimum magnitude image obtained by taking the pixel-wise minima across the magnitude images from different encodings, (b) the image in (a) with the thresholded pixels highlighted in red, (c, d, e) phase images in three encoding directions, Vx, Vy, Vz (f) the speed map and (g) the image in (f) with the thresholded pixels highlighted in red. The discarded pixels have either small magnitude (for one or more velocity components) or insignificant flow
