Synopsis

Scout Accelerated Motion Estimation and Reduction (SAMER) is a novel technique that can mitigate motion artifacts in MR images. In this study, we compared the brain volume and cortical thickness measurements obtained from in vivo motion-free, motion corrupted, and motion corrected images acquired with SAMER to those from a motion-free standard MPRAGE reference scan. The quantitative analysis of motion-free and motion corrected SAMER images showed comparable results with motion-free standard MPRAGE.
