Production of Radioisotopes for Imaging and Therapy at Low Energy

The production of radioisotopes for use in biomedical procedures such as diagnostic imaging and/or therapeutic treatments is achieved through nuclear reactions in reactors or from charged particle bombardment in accelerators. In reactors the nuclear reactions are initiated with neutrons while in accelerators the typical charged particle reactions utilize protons although deuterons and α−particl...

Production and Selection of Metal PET Radioisotopes for Molecular Imaging

A new adrenal computer imaging technique using dual-radioisotopes.

Computer processed adrenal imaging using dual-radioisotopes, 6 beta-iodomethyl-19-nor-cholest-5(10)-en-3 beta-ol-131I and 99mTc-phytate was performed in 12 patients with primary aldosteronism and 4 with Cushing's syndrome due to adrenocortical tumor. Adreno-photoscanning and hepato-photoscanning were performed in the same position 2-4 days following intravenous administration of radiocholestero...

Radioisotopes produced by neutron irradiation of food.

The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only dominant under certain conditions. The com...

Radioisotopes in Medicine

Nuclear medicine uses radiation to provide diagnostic information about the functioning of a person's specific organs, or to treat them. Diagnostic procedures are now routine.. Radiotherapy can be used to treat some medical conditions, especially cancer, using radiation to weaken or destroy particular targeted cells. Millions of nuclear medicine procedures are performed each year, and demand fo...
