k-t accelerated aortic 4D flow MRI in under 2 minutes: feasibility and impact of resolution, k-space sampling patterns, and respiratory navigator gating on hemodynamic measurements

PURPOSE: To assess the performance of highly accelerated free breathing aortic 4D flow MRI acquired in under 2 minutes compared to conventional respiratory gated 4D flow. METHODS: Eight k-t accelerated non-gated 4D flow MRI (PEAK GRAPPA, R=5, TRes=67.2ms) using four k(y)-k(z) Cartesian sampling patt...
