Clinical Trial Summary

The objective of this study is to nake a comparison between 11c-acetate and 11c-acetoacetate kidney uptake in chronic kidney failure patients.

Description:

Chronic kidney failure patients will be ask to perform two positron emission tomography scan during the same day. One, with a 11C-Acetate Tracer and the other with 11C-Acetoacetate. The results will allow to determine the difference between the two tracers and will ultimately be compared with precedent results of healthy controls.
