  1. Note—Reported values are the ranges (minima and maxima) for each parameter. Parameters were tailored to each individual’s anatomy and the field strength used. Two sets of images were reconstructed for each 4D flow acquisition: a high-resolution image set used to compute flow and ventricular KE, and a low-resolution image set used to separate LV flow components by tracking pathlines
