MR‐assisted PET motion correction in simultaneous PET/MRI studies of dementia subjects

Background Subject motion in positron emission tomography (PET) studies leads to image blurring and artifacts; simultaneously acquired magnetic resonance imaging (MRI) data provides a means for motion correction (MC) in integrated PET/MRI scanners. Purpose To assess the effect of realistic head motion and MR‐based MC on static [ 18 F]‐fluorodeoxyglucose (FDG) PET images in dementia patients. Study Type Observational study. Population Thirty...
