4D Flow MRI velocity mapping, generated from time-resolved 3D phase-contrast imaging data, is available for the assessment of complicated flow pattern in cerebrovascular diseases. The main disadvantage of 4D Flow MRI is its lengthy scan time. We assessed the feasibility of@4D Flow MRI combined with two acceleration techniques, y-z radial sampling and k-t SENSE, by comparing with the standard 4D Flow MRI using SENSE. Y-z radial sampling was feasible for the quantification of peak systolic velocity and flow volume, whereas k-t SENSE was feasible for the 4D flow visualization.
