Effects of magnetic field under gradient echo echo planar imaging (GE-EPI) on the cerebral microcirculation. (A) Maximal effects of magnetic field under GE-EPI on BOLD signal at position A during functional brain mapping at slice gradient = 40 mT/m for all MR systems (see 'Supplementary Method 4' in Additional file 1). (B) Maximal effects of magnetic field under GE-EPI on FAIR signal at position A during functional brain mapping at slice gradient = 40 mT/m for all MR systems (see 'Supplementary Method 5' in Additional file).
