Imaging of Fibroblast Activation Protein in the Microenvironment of Tumors by 18F‑Labeled Positron Emission Tomography Tracers with Increased Polarity
{{output}}
Fibroblast activation protein (FAP) is a serine protease that is highly expressed by fibroblasts in the microenvironment of tumors. Therefore, it represents a promising target for molecular imaging and therapy of tumors. 68Ga-chelator-based PET tracers address... ...
