Summary

Motion artifacts lower MRI quality, but their contributing factors and effect on diagnostic accuracy are unclear. This Danish single-center retrospective study of suspected stroke patients found that motion artifacts in brain MRIs significantly decrease both human and AI detection of intracranial hemorrhages.
