Dynamic PET imaging enables absolute quantification of myocardial blood flow (MBF). However, motion of the heart during imaging deteriorates the accuracy of PET MBF measurements. Simultaneous MR/PET makes it possible to compensate PET images for motion by incorporating MR-based motion information inside the PET reconstruction process. In this study, we propose and assess the impact of a tagged-MRI based PET motion-correction technique for improved PET MBF quantification using an in-vivo simultaneous MR/PET study.
