Upon administration of fluorine F 18 dasatinib, dasatinib targets and binds to Bcr/Abl, SRC-family protein-tyrosine kinases, c-Kit and platelet-derived growth factor receptor (PDGFR). Upon binding, the fluorine F 18 moiety allows PET imaging of tumor cells and can be used as a tracer for the biodistribution of dasatinib."}]
