Based on the images and biodistribution obtained from micro-PET/CT imaging, RT-112 (FGFR1-high expression) xenografts displayed significantly higher tumor uptake of [18F]F-FGFR1, as well as higher T/M, T/L and T/K values than those in A549, SNU-16 and Calu-3 xenografts (FGFR1-low expression), especially at 30 min after injection. This evidence concerns the gene FGFR1 and neoplasm.
