Distributions of radioactivity and TSPO expression in control and CCl4-treated rat livers.
Autoradiographic images of liver sections 1 h after injection of [18F]FEDAC are shown in (A) and (B) for control rats and rats treated with CCl4 for 6 weeks, respectively. Immunofluorescence staining of TSPO using the same sections as in (A) and (B) are shown in (C) and (D) for control rats and rats treated with CCl4 for 6 weeks, respectively. The distribution of radioactivity from [18F]FEDAC correlated well with the netlike appearance of TSPO expression in the hepatic lobules (B,D). Scale bar: 1 mm.
