WebJul 1, 2024 · Subject motion during fMRI scans reduces statistical significance of the activation maps and increases the prevalence of false activations. Motion correction is therefore an essential tool for a successful fMRI data analysis. WebThe phase-encoding direction is associated with two major artifacts: wrap-around and flow/motion. Wrap-around (also called aliasing) occurs when the size of the body part imaged exceeds the defined field-of-view (FOV) in the phase-encode direction.This causes anatomy outside the FOV to be folded in over the main part of the image.
