Abstract

An automated module for the synthesis of L-[11C-methyl]methionine, a well-known PET radiotracer for brain tumor imaging, has been designed. The module meets modern requirements for the production of radiopharmaceuticals and radiation safety; thanks to the original program created in the Delphi programming environment, module is convenient for the synthesis control (user-friendly) and operation; the service can be maintained on its own with minimal time and nancial costs. The module ensures the production of L-[11C-methyl]methionine with high chemical, radiochemical and enantiomeric purity and a radiochemical yield of 30% (based on [11C]CO2 activity, not decay corrected).
