Summary
This review covers positron-emitting radionuclides for Positron Emission Tomography (PET) imaging. It highlights cyclotron-produced
Area of Science:
- Nuclear medicine and radiochemistry
- Biomedical imaging technologies
- Medical research applications
Background:
- Positron Emission Tomography (PET) relies on positron-emitting radionuclides for molecular imaging.
- Traditional PET radionuclides include Carbon-11, Nitrogen-13, Oxygen-15, and Fluorine-18.
- Onsite production of radionuclides using biomedical cyclotrons is crucial for timely research.
Purpose of the Study:
- To review the production and applications of positron-emitting radionuclides for PET.
- To emphasize radionuclides producible with biomedical cyclotrons.
- To highlight emerging 'non-standard' PET radionuclides gaining research interest.
Main Methods:
- Literature review of scientific publications on PET radionuclides.
- Focus on radionuclides suitable for onsite cyclotron production.
- Discussion of established and novel positron emitters.
Main Results:
- Established PET radionuclides (C-11, N-13, O-15, F-18) are foundational but have limitations.
- Non-standard PET radionuclides offer alternative or complementary imaging capabilities.
- Biomedical cyclotrons facilitate the production of a wider range of PET isotopes.
Conclusions:
- Onsite cyclotron production enables broader access to diverse PET radionuclides.
- Non-standard PET radionuclides are expanding the scope of molecular imaging research.
- Continued development in radionuclide production and application is vital for advancing PET.
