PURPOSE: A 2D image navigator (iNAV) based 3D whole-heart sequence has been used to perform MRI and PET non-rigid respiratory motion correction for hybrid PET/MRI. However, only the PET data acquired during the acquisition of the 3D whole-heart MRI is corrected for respiratory motion. This study introduces and evaluates an MRI-based respiratory motion correction method of the complete PET data. METHODS: Twelve oncology patients scheduled for an additional cardiac 18 F-Fluorodeoxyglucose (18 F-FDG) PET/MRI and 15 patients with coronary artery disease (CAD) scheduled for cardiac 18 F-Choline (18 F-FCH) PET/MRI were included...
