Figure 2:

Representative steady-state free precession short-axis cine images of pulmonary artery demonstrate calculation of the quantitative metrics pulmonary arterial relative area (left), with systolic pulmonary artery size shown as solid line and diastolic pulmonary artery size shown as dotted line, ventricular mass index (middle), with right ventricular mass shown as dotted area and left ventricular mass shown as solid lined area, and interventricular septal angle (right), shown by solid line. LV = left ventricle, RV = right ventricle.
