WebbNucleophilic [ 18 F]fluoride ions are generated through irradiation of ‘heavy’ water ( [ 18 O]H 2 O) via the nuclear reaction 18 O (p,n) 18 F. Fluoride ions are generally poorly nucleophilic in water ( Hefter and McLay, 1988) however, rigorous drying procedures enables the use of [ 18 F]fluoride as a nucleophile in radiolabeling experiments. WebbFluorine-18 (18 F, T 1/2 = 109.7 min) is a positron-emitting isotope that has found extensive application as a radiolabel for positron emission tomography (PET).Although gaseous 11 C CO 2 and 11 C CH 4 are practically transported from cyclotron to radiochemistry processes, 18 F-fluoride is routinely transported in aqueous solution …
