From: Cardiovascular magnetic resonance 4D flow analysis has a higher diagnostic yield than Doppler echocardiography for detecting increased pulmonary artery pressure

Fig. 1

Schematic representation of the CMR 4D flow analysis method for estimation of PA pressure. Each of the boxes with red outline represent a single image from one time frame in the cardiac cycle. The boxes shaded red represent the time frames in which a vortex could be visualized. The top panels show a 3D vortex visualization of pulmonary flow in the right ventricle outflow tract orientation in a representative patient, with the black arrows denoting their location in the cardiac cycle. Visualization was performed using vector arrows, and the color scale denotes velocity of the respective vectors. RV – right ventricle, LV – left ventricle, PA – main pulmonary artery, PB – pulmonary bifurcation
