METHOD FOR PURIFICATION OF 18F-LABELED CHOLINE ANALOGUES

摘要

The present invention relates to a method for the purification of 18F-labeled choline analogues in a solution injectable to a patient, prepared using non-gaseous synthesis paths, comprising a step of solid phase extraction (SPE) purification using a solid support, wherein the solid support used in the solid phase extraction purification has the characteristic to retain impurities and reagents from the solution but not the 18F-labeled choline analogues
