Comparison of early and late Ga-FAPI-46-PET in 33 patients with possible recurrence of pancreatic ductal adenocarcinomas.

Positron emission tomography with Gallium (Ga) labeled inhibitors of fibroblast activation protein (Ga-FAPI-PET) is a promising imaging technique for patients with recurrent pancreatic ductal adenocarcinomas (PDAC). To date, it is not clear if different acquisition timepoints for Ga-FAPI-PET may result in comparable imaging information and if repetitive Ga-FAPI-PET imaging may add diagnostic value to single timepoint acquisition for recurrent PDAC. Here we analyzed retrospectively early (20 min p.
