Hepatic 18F-FDG, 18F-FAC, and 18F-DFA accumulation are affected in a mouse model of autoimmune hepatitis. (A) Histochemical and immunohistochemical analyses of liver sections from vehicle- and ConA-treated mice. Scale bars represent 50 microns. Transverse PET/CT images (B) and quantification (C) of vehicle- and ConA-treated mice injected with 18F-FDG, 18F-FAC, and 18FDFA. Livers are outlined in a white dotted line. Quantification represents radiotracer accumulation in the liver normalized to a background organ. Image courtesy of Salas J.R., Chen B.Y., Wong A., et al.
