A method is presented for retrospective rigid motion correction in multi-shot brain neonatal MR acquisitions. It is based on using parallel imaging so that the joint motion correction and image reconstruction problem becomes overconstrained. Additionally, no blurring is introduced in the presence of motion as no regridding is applied. The procedure has proven to significantly enhance the quality of neonatal brain images by decreasing the presence of confounding artifacts, improving the contrast, better resolving structures, and enabling the emergence of new anatomical details hindered by motion.
