Phase Contrast CMR and 4D Flow CMR assessment of pulmonary regurgitation post tetralogy of Fallot repair. a and b Show sagittal and coronal right ventricular outflow tract views used for planning of pulmonary through-plane flow. Red line demarcates the analysis plane. c and d Show quantifications of pulmonary flow by PCMR revealing significant regurgitant flow. e Shows significant pulmonary regurgitation by 4D Flow CMR. f Demonstrates quantification of pulmonary regurgitant flow by 4D Flow CMR
