Multi-Directional High Moment Encoded 3D PCMRA In-Vivo

Nicholas Ryan Zwart¹, James Grant Pipe¹

Signal to noise ratio gains in low VENC phase contrast MRI are limited by the ability to successfully unalias phase measurements that fall outside the -180 to 180 degree interval. A new time efficient acquisition and reconstruction method for unaliasing velocity encoded phase is compared to the well known 3-point (or dual-VENC) method in-vivo.
