Head motion is a significant challenge particularly for
neuroimaging studies of young and intellectually
impaired children. This study investigates the
application of a retrospective motion correction
algorithm for 3D T1-weighted imaging using MPnRAGE,
which is an inversion recovery prepared method with 3D
radial k-space sampling. This correction significantly
improved the quality of MPnRAGE images obtained on four
children that moved during their studies. The correction
did not cause any deleterious effects on image quality.
