A framework for motion correction of background suppressed arterial spin labeling perfusion images acquired with simultaneous multi-slice EPI

Abstract:

Purpose: When employing simultaneous multi-slice (SMS-) EPI for background suppressed (BGS-) arterial spin labeling (ASL), correction of through-plane motion could introduce artefacts, since the slices with most effective BGS are adjacent to slices with the least BGS. In this study, a new framework is presented to correct for such artefacts.

Methods: The proposed framework consists of three steps: (i) homogenization of the static tissue signal over the different slices to eliminate ...
