MRI with 4D flow permits to assess the hemodynamic parameters in a parent vessel and its branches inside the same sequence.
MRI with 4D flow permits to assess the hemodynamic parameters in a parent vessel and its branches inside the same sequence. The objective of the project is to compare the regurgitant fraction in the pulmonary artery (PA) measured using 4D MR-flow and standard 2D MR-flow in repaired Tetralogy of Fallot (rTOF) patients. The consistency of the 4D flow quantization will be assessed assuming mass conservation in the pulmonary artery tree (PA flow =LeftPA flow +RightPA flow ? ).

RECRUITINGRegurgitant fraction comparison
The primary objective of the project is to compare the regurgitant fraction in the pulmonary artery (PA) measured with 4D MR-flow and standard 2D MR-flow.
Time frame: Day 0
Right ventricular volume
The secondary objective is to compare the right ventricular volumes measured using the 4D prototype and the standard steady-state free precession sequences.
Time frame: Day 0
Pulmonary arteries flows
The consistency of the 4D flow quantization will be assessed assuming mass conservation in the pulmonary artery (PA) tree (PA flow =LeftPA flow +RightPA flow ? ).
