Production of reactive fluorine-18

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1986
Production conditions are reviewed from the perspective of maximizing activity--both total and specific--of 18F as electrophilic or nucleophilic precursors, with minimal levels of interfering species. Careful target design can avoid many pitfalls, and telemetry of a few key variables can guide the way to reproducible yields, consistent with prediction.

Therapy Monitoring with Fluorine-18 FDG-PET and Fluorine-18 FDG-PET/CT

PET Clinics, 2008
PET with the glucose analog [18F]-FDG is increasingly used to monitor tumor response in patients undergoing chemotherapy and chemoradiotherapy. The clinical value of FDG PET for differentiation of residual tumor and therapy-induced fibrosis has been documented for gastrointestinal cancer.

Preparation of carrier-free fluorine-18

The International Journal of Applied Radiation and Isotopes, 1977
Abstract A method for the preparation of carrier-free fluorine-18 using a column of hydrous stannic oxide is described. The adsorption and desorption characteristics of the fluoride ion on the column has been investigated using F-18 as a tracer. The present study has confirmed that the fluoride ion is practically completely adsorbed on the column in ...

The Preparation of Fluorine-18 Labelled Radiopharmaceuticals

The International Journal of Applied Radiation and Isotopes, 1977
Abstract Progress in the preparation of fluorine-18 labelled radiopharmaceuticals is reviewed. The pharmacology and design of 18F-labelled organic compounds of biomedical interest, production of the radionuclide and methods of labelling which have been used to date are discussed. Emphasis has been placed on the practical chemical problems encountered,

Preparation of Fluorine-18

Journal of Nuclear Science and Technology, 1964
Fluorine-18 was prepared by neutron irradiation of lithium carbonate in the reactor JRR-1. Five grams of lithium carbonate was irradiated for 2hr with a thermal neutron flux of 6×1011 n/cm2/sec. An alumina column was used to separate 18F from the irradiated material.
