  1. All values are mean flow per heart beat ± standard deviation (mL). 1 – P < 0.05 for MPA flow compared to Cine 2D bSSFP right ventricular stroke volume. 2 – P < 0.05 compared to 4D flow. Differences in flow pre- and post-embolization were not significant (P ≥ 0.05). Abbreviations – MPA Main pulmonary artery, RPA Right pulmonary artery, LPA Left pulmonary artery.
