Radioactive tracer uptake of livers from WHV-induced HCC woodchuck model using 18F-glucose (FDG), 11C-acetate and 11C-choline. (a) Representative imaging of an animal with WHV-induced HCC in which the uptake of FDG was negative while the uptake of 11C-acetate and 11C-choline were positive. (b) After radiofrequency ablation (RFA) of the tumor the uptake of FDG and 11C-acetate were lower than the surrounding liver tissue.
