Özet

Fibroblast activation protein (FAPI), a type II transmembrane glycoprotein is a promising target to image epithelial originated cancers. Pancreatic cancer is characterized with [68Ga]Ga-FAPI-04 and 18F-fluorodeoxyglucose (18F-FDG) uptake in varying degree. However physiologic uptake and uptake associated with acute/chronic pancreatitis makes interpretation challenging. We would like to present a case of pancreatic cancer whose tumor could not delineated from rest pancreatic tissue in [68Ga]Ga-FAPI-04 positron emission tomography/computed tomography (PET/CT) images due to intense FAPI uptake in whole pancreas but more remarkable in 18F-FDG PET/CT images.
