Quantitative gas-phase separation of carrier-free thallium radioisotopes from proton-irradiated [Formula: see text] [PDF]

open access: hybridJournal of Radioanalytical and Nuclear Chemistry
Carrier-free [Formula: see text] was thermally separated from proton-irradiated [Formula: see text] . Pressed [Formula: see text] targets were irradiated with [Formula: see text] protons at the IP2 beamline of the high-intensity proton accelerator facility at the Paul Scherrer Institute.

Evaluation of myocardial infarction by radioisotope myocardial imaging with special reference on thallium-201 myocardial perfusion imaging.

open access: bronzeJapanese Circulation Journal, 1981
One hundred and three patients with myocardial infarctions were studied with 201-thallium chloride and/or 99m-technetium pyrophosphate myocardial imaging and were followed-up for an average of 23 months. There were 24 false negative cases with 201-thallium chloride, but no deaths or serious complications occurred during the follow-up period in these ...
