99mTc-Technetium Shortage: Old Problems Asking for New Solutions

Autor: Luis F. Metello

Publikováno v: Journal of Medical Imaging and Radiation Sciences. 46:256-261

Technetium 99-metastable ( 99m Tc) is the most important radionuclide, responsible for more than 80% of applications in nuclear medicine, with more than 40 million procedures being performed each year, worldwide, in all major clinical fields. It deca

Cyclotron Production of Unconventional Radionuclides for PET Imaging: the Example of Titanium-45 and Its Applications

Autor: Pedro Costa, Luís F. Metello, Francisco Alves, M. Duarte Naia

Publikováno v: Instruments, Vol 2, Iss 2, p 8 (2018)

Positron emitting radionuclides are used to label different compounds, allowing the study of the major biological systems using PET (positron emission tomography) imaging. Although there are several radionuclides suited for PET imaging, routine clini
