Patient motion can degrade diagnostic image quality to the point that scans must be re-acquired, or patients called back. In this work, we performed a systematic clinical evaluation of SAMER, a highly efficient retrospective motion mitigation approach. 62 patients from emergency and inpatient care settings were scanned at 3T, and 14 cases were identified with a range of patient motion. Two neuro-radiologists performed blinded review of the images before and after motion correction, rating the images for motion severity. In 13 of the 14 cases, reduced motion severity and improved visualization of anatomy/pathology was obtained after SAMER motion mitigation.
