To compare the effect of implanted medical materials on (18)F-fludeoxyglucose ((18)F-FDG) positron emission tomography (PET)/MRI using a Dixon-based segmentation method for MRI-based attenuation correction (MRAC), PET/CT and CT-based attenuation-corrected PET (PETCTAC). ⋯ Being aware of the morphology of artefacts owing to implanted medical materials avoids interpretation errors when reading PET/MRI.
