DOI: 10.1002/nbm.4185
Abstract: Multi‐shot techniques offer improved resolution and signal‐to‐noise ratio for diffusion‐ weighted imaging, but make the acquisition vulnerable to shot‐specific phase variations and inter‐shot macroscopic motion. Several model‐based reconstruction approaches with iterative phase correction have been… read more here.
