Abstract

See full text

A PET imaging agent is made, by at first, washing out fluoride ions (F-18) adhered on an ion exchange resin to a reaction vessel with potassium carbonate/Kryptofix 2.2.2 in acetonitrile-water. After processing the first azeotropic distillation with helium while water is removed, the temperature is cooled down. Then, acetonitrile is added to the reaction vessel to be heated up. After processing the second azeotropic distillation with helium while water is removed, the temperature is cooled down and excess water is extracted. A precursor is then added to the reaction vessel to be heated up for processing a fluorination reaction. The reaction mixture obtained after the fluorination reaction is cooled down to be flown through a solid-phase extraction column with waste drained into a waste tank. Then, ethanol is used to wash out a product, i.e. [F-18]FEONM, adsorbed by the column, to be collected in a collection vial.
