Motion poses a significant problem for PET imaging. Here, we present an MR-based rigid-body motion correction approach for neurological MR-PET studies with hybrid MR-PET scanners. Motion data are extracted from an EPI time-series and are used to correct the PET images for motion with minimal additional processing time required. Preliminary in vivo results show a clear resolution recovery in the PET images.
