Single filed PET/CT imaging at 5 minutes after the whole body scan revealed a left lobe liver lesion. The patient took 2 g vesicant with 300 mL water 5 minutes before whole body PET/CT imaging. The change of gastric contents between CT and FDG PET data acquisition may induce a misregistration artifact. The PET/CT misregistration artifact due to vesicant and water loading can be demonstrated by an immediate single filed PET/CT acquisition.3enjournal article
