One aspect of the present invention relates to a method of preparing radiofluorinated substituted alkyl, cycloalkyl, aryl, and alkenyl compounds. In a preferred embodiment, potassium fluoride-18 is used. Another aspect of the invention relates to piperazine compounds containing fluorine-18 that are useful as imaging agents. In certain embodiments, the piperazine compounds contain a quaternary amine. Another aspect of the invention relates to arylphosphonium compounds containing fluorine-18 that are useful as imaging agents. In certain embodiments, the phosphonium compound is a tetraaryl phosphonium sait. Another aspect of the present invention relates to a method of obtaining a positron emission image of a mammal, comprising the steps of administering to a mammal a compound of the invention, and acquiring a positron emission spectrum of the mammal.
本发明的一个方面涉及一种制备放射性氟代取代烷基、环烷基、芳基和烯基化合物的方法。在一个首选实施例中,使用氟-18钾。该发明的另一个方面涉及含氟-18的哌嗪化合物,用作成像剂。在某些实施例中,哌嗪化合物含有季铵胺基。该发明的另一个方面涉及含氟-18的芳基磷酸铵化合物,用作成像剂。在某些实施例中,磷酸铵化合物是四芳基磷酸铵盐。本发明的另一个方面涉及一种获得哺乳动物正电子发射图像的方法,包括向哺乳动物施用本发明的化合物,并获取哺乳动物的正电子发射谱。
