Flow-MRF is a highly promising technique for rapid quantification of both relaxation times and time-resolved flow velocities. However, this method currently suffers from two major drawbacks, firstly a low efficiency since multiple shots are used and secondly strongly increased velocity noise for low velocities due to magnetization preparation pulses. This abstract targets both issues by presenting an optimized the flip angle (FA)-pattern for Flow-MRF, while assuming periodic boundary conditions.
