Abstract

The present invention relates to a method for purification of 18F-labeled choline analogs 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 analogs.
