The purpose of this work was to evaluate the use of 3D
multi-echo flow compensation for improved multi-echo
susceptibility-weighted imaging, to extend a concept for
partial flow compensation to multi-echo imaging and to
perform a direct comparison between complete and partial
flow compensation methods. The inclusion of 3D
multi-echo flow compensation is shown to improve
arterial depiction in the combined
susceptibility-weighted images. Partial flow
compensation is shown to provide substantial
improvements while not requiring as much of a compromise
in terms of echo spacing as complete flow compensation.
