    摘要: A method for synthesizing an 18F-labeled probe. The method includes a step of eluting an amount of 18F with a first solvent which includes a predetermined amount of water and at least one organic solvent. In this step, the 18F elutes as an 18F solution. The method also includes a step of using the 18F solution to perform 18F-labeling in the presence of at least one labeling reagent and at least one phase transfer catalyst so as to generate the 18F-labeled probe. In the method, there is no step of drying the 18F starting from a time when the eluting step is performed and ending at a time when the 18F-labeling step is performed.

    摘要: A method for generating a radiolabeled tracer. The method includes providing a phosphine molecule having at least one carbocyclic, aromatic, or pyrrolidinyl ring with an OH substitute. The OH of this phosphines molecule is then condensed with an acid to produce a phosphine ester. Staudinger ligation is then performed to generate the radiolabeled tracer by treating the phosphine ester with a radiolabeled azide having a PET radioisotope moiety.
