Synopsis

Keywords: Blood vessels, Velocity & Flow, Neuro4Dflow has become a widely used sequence for dynamical characterization of the vascular system. This work shows that it is feasible to implement Leapfrog to acquire results that are colse to those obtained with Finite Volume Methods with excelent results in velocity, vortex and energy, but with certain limitations when estimating the WSS. In order to diminish the acquisition time, we will implement a postprocessing tool using only a 2D Phase Contrast acquisition and implement FSI (CFD), this results will be compared with those given by the LF method.
