Quantification of left and right ventricular kinetic energy using four-dimensional intracardiac magnetic resonance imaging flow measurements
Key result
Four-dimensional phase-contrast MRI demonstrated that peak systolic kinetic energy was lower in the left ventricle than the right ventricle (4.9 vs 7.5 mJ, P=0.004).

Implication
4D MRI kinetic energy metrics are hypothesis-generating; prospective studies needed before any clinical application.

Outcome
Kinetic energy (KE) during the entire cardiac cycle of the left ventricle (LV) and right ventricle (RV)surrogate
Four-dimensional phase-contrast MRI reveals distinct kinetic energy patterns between the left and right ventricles, suggesting LV filling is more dependent on ventricular suction while RV systolic energy is higher due to its longer outflow tract.

Carlsson et al. (2011) conducted a cross-sectional in Healthy volunteers (n=9). Four-dimensional phase-contrast magnetic resonance imaging (MRI) was evaluated on Kinetic energy (KE) during the entire cardiac cycle of the left ventricle (LV) and right ventricle (RV). Four-dimensional phase-contrast MRI demonstrated that peak systolic kinetic energy was lower in the left ventricle than the right ventricle (4.9 vs 7.5 mJ, P=0.004).
