Radionuclide candidates for β+γ coincidence PET: An overview.

Following the advancement of the Positron Emission Tomography (PET), a novel technique emerged which takes advantage of the gamma quanta emitted, in some cases, after the β+ decay. While 44gSc is commonly agreed the best choice to validate this new modality, other radioisotopes must also be considered in the future. We present them in this paper, along with their possible applications, properties and the optimal production routes with the use of the accelerators.
