Characterization of the benign lesions with increased 68Ga-FAPI-04 uptake in PET/CT

The objective of the study was to characterize benign lesions showing increased 68Ga-FAPI-04 uptake on FAPI PET/CT. We retrospectively reviewed 182 patients with suspected various cancers who were performed 68Ga-FAPI-04 PET/CT imaging from August 2020 to December 2020. The diagnoses of the benign lesions were made by the CT findings (CT), other imaging information (OII) (contrast enhance CT, FDG PET, ultrasound, MRI or others), clinical...
