      abstract     = {Head motion is a major source of image artefacts in
                      neuroimaging studies and can lead to degradation of the
                      quantitative accuracy of reconstructed PET images.
                      Simultaneous magnetic resonance-positron emission tomography
                      (MR-PET) makes it possible to estimate head motion
                      information from high-resolution MR images and then correct
                      motion artefacts in PET images. In this article, we
                      introduce a fully automated PET motion correction method,
                      MR-guided MAF, based on the co-registration of multicontrast
                      MR images. The performance of the MR-guided MAF method was
                      evaluated using MR-PET data acquired from a cohort of ten
                      healthy participants who received a slow infusion of
                      fluorodeoxyglucose ([18-F]FDG). Compared with conventional
                      methods, MR-guided PET image reconstruction can reduce head
                      motion introduced artefacts and improve the image sharpness
                      and quantitative accuracy of PET images acquired using
                      simultaneous MR-PET scanners. The fully automated motion
                      estimation method has been implemented as a publicly
