How much, and in which directions, do subjects move during MRI scans?
Motivation: Subject motion can cause artifacts in MR images and biases in subsequent quantification. Goal(s): A thorough characterization of motion across multiple cohorts/consortiums has not been performed, particularly with diffusion MRI data. Approach: We use diffusion MRI data from 14,440 subjects from 10 consortiums (aged 0-100) to characterize (1) how much subjects move during scanning; (2) what kind of head motion is most common; (3) whether motion increases as acquisition proceeds; (4) if motion is associated with age; or (5) with cognitive decline. Results: Knowledge of the magnitude and direction of motion provides guidance for motion mitigation strategies and informed preprocessing strategies. Impact: Subject motion induces artifacts and biases in MR images. Characterizing motion magnitude and directions, as well as motion correlates, informs and improves motion mitigation strategies and image processing pipelines.
