The present disclosure relates to a compound comprising at least one of a carbon or an oxygen isotope and a process for preparing the compound. The process comprises irradiating a compound comprising at least one of a carbon or an oxygen atom using photons or particles having an energy in the range of 20 MeV-430 MeV. The carbon and/or the oxygen atom is then allowed to be converted into a carbon and/or an oxygen positron nuclide through a photonuclear reaction. Provided that the molecular structure of the compound is not disrupted, the compound comprising the carbon and/or the oxygen isotope is prepared. The compound may be used in positron and/or other nuclide imaging to obtain a distribution and/or metabolic image of the compound in a human and/or animal body.
A process, comprising:
A compound comprising at least one of a carbon or an oxygen isotope prepared by irradiating a compound comprising at least one of a carbon atom or is an oxygen atom utilizing irradiation energy in the range of 20 MeV-430 MeV and allowing the at least one of the carbon atom and the oxygen atom to convert to at least one of a carbon positron nuclide and an oxygen positron nuclide through a photonuclear reaction.
A composition comprising a compound comprising at least one of a carbon or an oxygen isotope prepared by irradiating a compound comprising at least one of a carbon atom or an oxygen atom utilizing irradiation energy in the range of 20 MeV-430 MeV and allowing the at least one of the carbon atom and the oxygen atom to convert to at least one of a carbon positron nuclide and an oxygen positron nuclide through a photonuclear reaction.
