We
present a method for improving the VNR in 3D radial undersampled phase
contrast exams using an accelerated dual Venc acquisition. This method will allow for more accurate
velocity measurements and advanced hemodynamic analysis, particularly in
vascular areas that have wide ranges of velocities of interest such as arterial
and venous systems .
