The potential of a recently proposed single-shot methodology, SPatio-temporal ENcoding (SPEN), was explored towards brain diffusion imaging on a 7T whole-body scanner. To better evaluate this imaging performance, studies were repeated at 3T, and done in parallel with diffusion-weighted SE-EPI scans. In both axial and coronal scans, SPEN evidenced a higher robustness to overcome the B0-inhomogeneities that arise particularly at 7T and also at 3T. The diffusion measurements of the brain showed fair agreement between both acquisitions methods, even despite the slight differences evidenced between the 3T and 7T ADC maps.
