Flow quantification with MRI in patients with congenital heart disease (CHD) is frequently difficult to perform and time consuming because of the complex anatomy. 4D flow-sensitive phase contrast (PC) MRI has the potential to simplify the acquisition and quantification of flow information in patients with CHD. In this study we compared flow measurements through the aorta and main pulmonary artery in patients with CHD with a 3D radially undersampled, 3D PC MRI technique to standard 2D PC and 2D bSSFP measurements.
