It is feasible to calculate left ventricular kinetic energy using 4D flow MRI, demonstrating three distinct peaks during the cardiac cycle with low inter-scanner variability.
Supports 4D flow MRI for LV kinetic energy assessment across scanners; leaves open its diagnostic or prognostic utility.
Three-dimensional, three-component, time-resolved (4D) intracardiac flow can be visualized and quantified with velocity encoded phase contrast (PC) MRI. The kinetic energy content of the blood in the left ventricle (LV) during the cardiac cycle has previously not been described.
