A feasibility study of the therapeutic application of a mixture of ^67/64 Cu radioisotopes produced by cyclotrons with proton irradiation. [PDF]

Med Phys, 2022
Abstract Purpose 64Cu and 67Cu radioisotopes have nuclear characteristics suitable for nuclear medicine applications. The production of 64Cu is already well established. However, the production of 67Cu in quantities suitable to conduct clinical trials is more challenging as it leads to the coproduction of other Cu isotopes, in particular 64Cu.

The innovative 52gMn for positron emission tomography (PET) imaging: Production cross section modeling and dosimetric evaluation

Medical Physics, Volume 50, Issue 3, Page 1843-1854, March 2023., 2023
Abstract Background Manganese is a paramagnetic element suitable for magnetic resonance imaging (MRI) of neuronal function. However, high concentrations of Mn2 + can be neurotoxic. 52gMn may be a valid alternative as positron emission tomography (PET) imaging agent, to obtain information similar to that delivered by MRI but using trace levels of Mn2 + ,
