We present a realistic vascular model based on Monte-Carlo modeling of diffusion and the finite element method to compute the background magnetic field of partly oxygenated finite venules exposed to up to 16.4 T. Our data show that the realistic vasculature data set is necessary to account for the effects due to finite-sized vessels. The venule data herein stems from 2 photon microscopy of the rat brain. Results show that the infinite vessel model is prone to error so that the use of realistic vascular data sets is necessary to get precise results. However, for a better understanding more realistic vascular data sets should be examined in future work.
