In this study we investigate the feasibility of FDG PET/MR as a platform for whole body dynamic quantitative PET imaging. The ability of PET/MR systems to provide truly simultaneous imaging is advantageous compared to PET/CT for serial whole body PET acquisitions in that simultaneously acquired MR images can provide additional information to PET data, such as the application of motion parameters estimated from MR images to PET images to correct for misregistration which is not possible with PET/CT. Further improvements in workflow can allow integration of multiple MR contrasts, making dynamic whole body PET/MR a highly feasible and compelling methodology.
