10-year-old male patient with surgical correction of tetralogy of Fallot (non-reformatted coronal view). A flow-related artifact (most likely due to incorrect fat-water separation) is seen on non-contrast-enhanced REACT-CMRA (A, water-only reconstruction; fat-only and in- and opposed phase reconstructions are not available) within the main pulmonary artery (arrow), but neither on contrast-enhanced steady-state-CMRA (B) or first-pass-CMRA (C). Phase-contrast flow measurement revealed moderate pulmonary valve stenosis (pulmonary valve maximum blood velocity: 3.1 m/s). Background suppression of thymus tissue was more efficient on steady-state- than REACT-CMRA (asterisks)
