Küstner T, et al. – Researchers sought to establish a motion correction for Positron–Emission–Tomography (PET) using simultaneously acquired magnetic–resonance (MR) images within 90 s. The proposed method serves a clinically feasible setup for respiratory and cardiac motion correction of PET data by simultaneous short–term magnetic resonance imaing. It was demonstrated that the acquisition sequence and all reconstruction steps are publicly available to foster multi–center studies and various motion correction scenarios.
