In this work we report results from a large pediatric study that shows the effect of motion. Motion patterns were measured on 82 children, mean age 13.4 years, in a T1 weighted brain MRI. An expert radiologist graded the images using a 4-point scale ranging from clinically non-diagnostic to no motion artifacts. We used these grades to correlate motion parameters such as maximum motion, mean displacement from a reference point and motion free time. The results will help the motion correction community in better understanding motion patterns in pediatric populations and how it effects image quality.
