The potential usefulness of [C-11]-labeled alpha-aminoisobutyric acid (AIB) for tumor imaging has been demonstrated previously in our findings of increased tumor uptake with C-14-labeled AIB in human melanoma heterotransplants in nude mice, and subse

In some biological experiments aimed at evaluating the localized effect of radiation on specific parts or organs of animals, x-ray fields of about 1.0 to 1.5 cm. diameter must be used. Typical examples are the irradiation of tumor implants in mice or

Selenium-73 was produced in a cyclotron by irradiation of germanium with 3He. 4–8 mCi were obtained by 2-h bombardment with a 20-μA beam. Carrier-free selenate and selenite were prepared by chemical processing. Distribution of this isotope was stu

A method is described for the production of 18F as fluoride ion in aqueous solution. Pure water (10 ml) is irradiated with 22 MeV 3He ions from an isochronous cyclotron. The yield is 6mCi/μAh or 70 mCi in 30 min with a beam current of 25 μA. Impuri
