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.
