Flow patterns in the right atrium, right ventricle and central pulmonary arteries, visualized with four-dimensional, flow-sensitive phase-contrast MRI, are dramatically different from those in normal, healthy volunteers. Analysis of these altered flow patterns may provide a better understanding of the interactions between pulmonary artery hypertension and right heart failure.
