Reference values for fluorine-18-fluorodeoxyglucose and fluorine-18-sodium fluoride uptake in human arteries

Nuclear Medicine Communications, 2017
Reference values of fluorine-18-fluorodeoxyglucose (F-FDG) and fluorine-18-sodium fluoride (F-NaF) uptake in human arteries are unknown. The aim of this study was to determine age-specific and sex-specific reference values of arterial F-FDG and F-NaF uptake.Uptake of F-FDG and F-NaF was determined in the ascending aorta, aortic arch, and descending ...

SPECT imaging of fluorine-18.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1995
The objective of this work was to determine the potential clinical usefulness of SPECT to image 511-keV annihilation photons.A triple-headed gamma camera equipped with ultra-high-energy collimators was used to image 18F. Sensitivity measurements were carried out and the FWHM and FWTM were determined in air and for a unit-density scattering medium ...

A radiosynthesis of fluorine-18 fluoromisonidazole.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1989
A new preparation of [18F]fluoromisonidazole [1H-1-(3-[18F] fluoro-2-hydroxypropyl)-2-nitroimidazole] is presented as a two-step, two-pot reaction sequence. The method is useful for the production of 20-30 mCi quantities of this compound from [18F]fluoride, available in 40% radiochemical yield at end of bombardment (EOB) with a specific activity (nca ...

The standardisation of fluorine-18.

Australasian physical & engineering sciences in medicine, 1996
The Australian Nuclear Science and Technology Organisation (ANSTO) maintains and disseminates the Australian standards of activity measurement. The standards include all nuclear medicine gamma-emitters and pure positron emitters. Calibration factors for the ANSTO 4 pi ionisation chamber for pure positron emitters have been traditionally determined from

Fluorine-18 labeling of proteins.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1987
Two fluorine-18-labeled reagents, methyl 3-[18F]fluoro-5-nitrobenzimidate and 4-[18F]fluorophenacyl bromide, have been prepared for covalent attachment of fluorine-18 to proteins. Both reagents can be prepared in moderate yields (30-50%, EOB) in synthesis times of 50-70 min.

Production of carrier-free fluorine-18

The International Journal of Applied Radiation and Isotopes, 1965
Abstract A rapid and effective procedure for the preparation of carrier-free fluorine-18 is described. The F 18 is produced by neutron irradiation of lithium carbonate and is separated by dissolving the material in acid and distilling off the hydrogen fluoride solution.

Myocardial viability studies using fluorine-18-FDG SPECT: a comparison with fluorine-18-FDG PET.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1997
Multidetector SPECT systems equipped with a high-energy, or 511-keV collimator, have been proposed to offer a less expensive alternative to PET in myocardial viability studies with [18F]FDG. The objectives of this investigation included: (a) measuring the physical imaging characteristics of SPECT systems equipped with either a high-energy general ...

Uptake of fluorine-18-fluorodeoxyglucose in sarcoidosis.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1994
Whole-body PET scanning was performed using 18F-fluorodeoxyglucose (FDG) in two patients with hilar lymphadenopathy in whom the clinical differential diagnosis was between sarcoidosis and lymphoma. Both patients were later proven to have sarcoidosis.
