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.
