Title: No-carrier-added [1.sup.11 c]putrescine

Abstract

The invention relates to a new radiolabeled imaging agent, no-carrier-added [1-.sup.11 C]putrescine, and to the use of this very pure material as a radiotracer with positron emission tomography for imaging brain tumors. The invention further relates to the synthesis of no-carrier-added [1-.sup.11 C]putrescine based on the Michael addition of potassium .sup.11 C-labeled cyanide to acrylonitrile followed by reduction of the .sup.11 C-labeled dinitrile. The new method is rapid and efficient and provides radiotracer with a specific activity greater than 1.4 curies per millimol and in a purity greater than 95%.
