Maps of through-plane velocity (a & c) and kinetic energy density (b & d) in selected left ventricular slices at peak systole in a control subject (left, a & b, 73-year-old male) and in an acute myocardial infarction patient (right, c & d, 73-year-old male). Positive though-plane velocities represent the apex-to-base direction. Velocities are lower in the mid-ventricle and apex of the acute MI subject compared to the control. The maps were created by registering 4D flow data to short-axis cine bSSFP images. The overlays were generated with ITK Snap
