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. The ability to unalias phase measurements on a per pixel basis is limited by errors in the measurements due to noise and signal biased phase. The method presented in this work is the combination of a multiple low VENC acquisition strategy and reconstruction algorithm that produces time efficient SNR in phase contrast MRI.
