4D Flow-MRI offers unique possibilities for the diagnosis of pulmonary hypertension. A validation of the sequence on a digital broadband 3T MR system is essential before introduction into clinical routine. This study compared 4D Flow–MRI derived stroke volume (SV) and maximal flow velocity (Vmax) in the pulmonary arteries of 23 healthy volunteers to 2D phase contrast MRI, right ventricular stroke volume (RVSV), conservation of mass-analysis (COM), and to a static phantom for additional error analysis. Results revealed clinically acceptable differences with a trend of phantom correction to improve results except for the COM-analysis.
