From: Quantification of diastolic vortex shape deformation in left ventricular filling from 4D flow MRI
(a) Frame (16/30) represents the Early filling (E) peak frame and the LV vortex ring appears almost completely circular. (b) Frame (28/30) represents Late filling (A) peak in which vortex is elongated and no longer circular but of more elliptical shape. View from FH direction. (c,d) shows their positions in E and A frames in LA view and shows that they are at the same position.
