Fig. 1From: Discriminating radiation injury from recurrent tumor with [18F]PARPi and amino acid PET in mouse modelsExperimental setup and hypothesis for imaging radiation necrosis and orthotopic brain tumors with [18F]FET-PET and [18F]PARPi-PET. Due to the molecular properties of each lesion and tracer, [18F]FET-PET will generate high lesion-to-background contrast in both tumor and radiation necrosis, while [18F]PARPi-PET will generate high contrast only in tumorBack to article page
