Abstract Introduction. Positron Emission Tomography (PET) is a non-invasive diagnostic tool that provides tomographic images and measures quantitative parameters of cell viability and metabolic activity of tissues. The most important used tracer in PET is an 18-F-Fluorodeoxy-glucose (FDG), the glucose molecule of which is labeled with a radiotracer and allows measurement and mapping of tissue glucose uptake. There are many studies in PET/CT which rely on some mammalian species, and recently on fish. Objective. The aim of this survey by using FDG-PET/CT are to optimize and determine FDG uptake in fish, in this case, common carp (Cyprinus carpio) using three treatments: Basic fish meal, Vita Pulvis and Probiotics s with two replications were used. Sphere Volume of interest (VOI) were drawn hand for the all organs, and standard uptake value (SUV) means were calculated. Results. The SUV mean for glucose uptake in the liver and gastrointestinal tract of fish were more similar to those of humans than rats or mice. SUV mean in fish fed by Probiotics ss in the major organ were less than those fed by Vita Pulvis and basic fish meal. The results present the opportunity to focus on studies of metabolism and screening for the effects of nutrients on body development.
