Developing sensitive diagnostic methods for a longitudinal evaluation of the status of liver fibrosis is a priority. This study is aimed at assessing the significance of longitudinal positron emission tomography (PET) imaging with 18F-labeling tracers for assessing liver fibrosis in a rat model with bile duct ligation (BDL). Twenty-one 6-week-old Sprague-Dawley male rats were used in this study. Longitudinal PET images using [18F]N-2-(2-fluoroethoxy)benzyl)-N-(4-phenoxypyridin-3-yl)acetamide ([18F]FEPPA) ( n = 3 ), [18F]fluoroacetate ([18F]FAc) ( n = 3 ), and 18F-fluoro-2-deoxy-D-glucose ([18F]FDG) ( n = 3 ) were obtained at 0, 1, and 2 weeks after BDL. Biochemical assays, histological assays, immunohistochemical staining assays, and next generation sequencing analyses were also performed at 0 ( n = 3 ), 1 ( n = 3 ), 2 ( n = 3 ), and 3 ( n = 3 ) weeks after BDL, which demonstrated the severe damage in rat livers after BDL. Regarding [18F]FEPPA and [18F]FDG, there was a significantly higher uptake in the liver after BDL (both  P &lt; 0.05 ), which lasted until week 2. However, the uptake of [18F]FAc in the liver was not significantly different before and after BDL ( P = 0.28 ). Collectively, both [18F]FEPPA and [18F]FDG can serve as sensitive probes for detecting the liver fibrosis. However, [18F]FAc is not recommended to diagnose liver fibrosis.
