PRELIMINARY EVALUATION OF FAPI-04-PET/CT FOR DIFFERENTIATING RECURRENCE AND POST-TREATMENT CHANGES IN HIGH-GRADE GLIOMAS

Preliminary evaluation of FAPI-04-PET/CT for differentiating recurrence and post-treatment changes in high-grade gliomas

Fibroblast-activated protein (FAP) expression in glial cells is attributed to FAP-positive foci on tumor vessels and neoplastic cells.Preclinical and pilot studies have shown FAP expression in high-grade gliomas.We aimed at Fans comparing PET imaging with FAP-inhibitor (FAPI-PET) with current standard, i.e., fluoro-ethyl tyrosine (FET) PET in post-
