Conservation of mass assessment for 2-D phase-contrast (PC) MRI and 4-D flow MRI. Plots assess conservation of mass (sum of flow through LPA and RPAvs. flow through MPA) for 2-D phase-contrast MRI (a) and 4-D flow (b). LPA left pulmonary artery, MPA main pulmonary artery, RPA right pulmonary artery
