The use of a highly accelerated, 3 dimensional, time-resolved, dual-venc phase-contrast acquisition is proposed for the assessment of hemodynamics in aneurysm models treated with different flow diverting devices. It is demonstrated that the use of a dual-venc technique is crucial to successfully depict the required velocity range and that flow conditions differ drastically between the different devices. The results give valuable insights into pre- and postinterventional flow conditions.
