4D flow imaging using phase contrast CMR (PC CMR) allows
visualization and quantification of blood flow. One of
the major limitations of 4D flow imaging is its long
scan time. In this study, we investigate an accelerated
4D flow imaging sequence that combines an efficient data
sampling strategy using echo planar imaging (EPI) with
randomly undersampled 3D k-space sampling pattern. The
randomly undersampled k-space data are then
reconstructed using compressed sensing (CS).
