Definitions

  • the present invention is directed to methods for producing [' 8 F] fluoride ion, and more particularly, methods for producing [ 18 F] fluoride ion using [ 18 O]oxygen gas.
  • Positron emission tomography is a unique diagnostic imaging modality that measures the time-dependent localized concentrations of radiopharmaceuticals labeled with position-emitting radionuclides within the human body.
  • Fluorine- 18 is used in the preparation of radiopharmaceuticals, such as 2-deoxy-2[ 18 F]fluoro-D-glucose (FDG), for PET imaging determinations.
  • FDG 2-deoxy-2[ 18 F]fluoro-D-glucose
  • Fluorine- 18 labeled fluoride ion has found widespread use in the synthesis of FDG for clinical use, but it is also used to produce a wide variety of other PET biological probes for research and clinical investigations of the brain, heart, and in the diagnosis of cancer.
  • Fluorine- 18 is commonly produced by proton irradiation of the stable oxygen- 18 isotope according to the 18 O(p,n) 18 F nuclear reaction.

  • Fluoride ion is generally used in nucleophilic substitution reactions, and fluorine gas is used in electrophilic reactions.
  • [ 18 F]fluoride ion is typically produced using liquid [ 18 O]water as the target material, and [ 18 F] fluorine gas is typically produced using [ 18 O]oxygen.
  • the standard method for the cyclotron production of aqueous [ 18 F]fluoride ion is by irradiation of [ 18 O]water using low-energy (10-17 MeN) protons according to the nuclear reaction 18 O(p,n) 18 F. (See Ruth, TJ. and Wolf, A.P. (1979), Absolute cross sections of the production of 18 F via the 18 O(p,n) 18 F reaction. Radiochim. Ada 26, 21-24.)
  • This reaction which uses the stable isotope oxygen-18 as the target material, offers a significantly higher yield than older deuterons-on-neon methods, giving about 188 mCi/ ⁇ A yield at saturation for 11 MeN protons.
  • the typical [ 18 O] water target holds about 0.35 to 1.2 mL of water, and using 20-30 ⁇ A beam current will easily yield cure-levels of [ 18 F] fluoride ion for a 60-120 minute bombardment.
  • this method suffers several drawbacks, including (I) the cost of the [ 18 O] ater (currently about $175/gram for 97% enriched, and $234/gram for 99% enriched), (ii) the limited availability of [ 18 O]water and the dependence of PET centers on foreign sources for the supply of this critical raw material, and (iii) target reliability and yield issues.
  • the [ 18 O]water is either separated from the [ 18 F] fluoride ion using a small trap-and-release anion exchange column with the recovered [ 18 O] water, containing metallic cations, being collected and saved, or is simply evaporated and lost as the first step in the radiochemical labeling process.

  • the solubilizing agent and produced [ 18 F]fluoride ion are removed from the enclosed chamber without opening the target.
  • the method of the invention offers several important advantages over the use of liquid [' 8 O] water.
  • gas targets are able to withstand relatively higher beam currents than small-volume [ l8 O] water targets, which translates to higher product yields and more reliable operation.
  • the [ 18 O]oxygen gas target material can also be efficiently recovered after the bombardment and can be recycled for subsequent runs.
  • the methods of the invention are superior to the method disclosed by Nickles et al. in that the present methods provide remote, automated recovery of the [ 18 F]fiuoride ion, thereby minimizing contact with radioactivity.
