WebMay 1, 2024 · A major limitation to structural and functional MRI (fMRI) scans is their susceptibility to head motion artifacts. Even submillimeter movements can systematically distort functional connectivity, morphometric, and diffusion imaging results. In patient care, sedation is often used to minimize head motion, but it incurs increased costs and risks. WebThe tool fsl_motion_outliers is designed to detect timepoints in an fMRI dataset that have been corrupted by large motion. It creates a confound matrix that can be used in the GLM to completely remove the effects of these timepoints on the analysis, without any adverse affects in the statistics. This is intended to deal with the effects of ...
