PDGFB and glioma: The aim of the study was to investigate (i) the growth dynamics with a special focus on identifying neuroimaging characteristics of the PDGFB-driven glioma mouse model using clinically relevant imaging methods, i.e., preclinical [18F]FET-PET/MRI, and (ii) to study features of the glioma-associated microenvironment by immunohistochemistry.
