DW-EPI at high diffusion gradients suffers from eddy current induced signal blurring and geometric distortion. In this study, concurrent monitoring of field evolution with NMR probes was implemented for HCP diffusion MRI acquisition at 7T. After image reconstruction with field correction, eddy current induced geometric distortion was largely removed, yielding similar level of correction obtained by data driven approaches such as EDDY. Signal blurring was further reduced than with EDDY. Future efforts will be made to quantify the impact on cortical tractography of this improved DW-EPI reconstruction.
