Fibroblast activation protein expression in the tumor microenvironment is crucial in survival prediction and differentiation of recurrent gliomas: a head-to-head comparison of 68Ga-FAPI-04 and 18F-FET in PET/CT imaging
26 Aug 2025
Abstract excerpt
The precise differentiation of recurrent glioma from treatment-related changes, such as pseudoprogression or radiation necrosis, is essential for treatment planning and remains a significant challenge. Fibroblast activation protein (FAP) expressed by cancer-associated fibroblasts can be targeted with PET tracers for in vivo visualization and quantification. This study aims to evaluate the diagnostic and...
