The present invention relates to a method for 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.
本发明涉及一种用于在溶液中纯化18F标记的
胆碱类似物的方法,该溶液可注射给患者,该方法使用非气态合成途径制备,包括使用固相萃取(
SPE)纯化步骤,使用固体支撑物进行固相萃取纯化,其中在固相萃取纯化中使用的固体支撑物具有保留溶液中的杂质和试剂但不保留18F标记的
胆碱类似物的特性。
