DW-EPI suffers from geometric distortion induced by eddy current from strong diffusion gradients. Magnetic field monitoring using 19F probes followed by algebraic reconstruction incorporating higher order field perturbation has been proposed to address such issue and was applied for single-band acquisition at 3T. In this study, this approach was implemented for high resolution multiband in vivo brain DW-EPI acquisition at 7T, taking into account of scanner imposed global phase modulation for eddy-current correction. Preliminary results showed successful correction of the geometric distortion across all diffusion gradients. Further investigation needs to be made to increase the SNR of DW images.
