Distribution kinetics and clearance of ¹⁸F-FLT (solid line) and ¹⁸F-FDG (dashed line) in mice bearing HCT116 human colorectal tumors after i.t. infusion of 5 MBq into the rear flank tumor. The radiotracer biodistribution kinetics were measured during 2 h by dynamic PET imaging. Data are expressed as the percent injected dose per gram of tissue (%IA/g). All data were corrected for physical decay of the isotope
