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.
