PET imaging

This article explores the significance of positron emission tomography (PET) imaging, particularly the use of radioactive glucose as a radiotracer. It examines the process of creating radiotracers and how they interact within a magnetic field, emphasizing the principles of beta-plus and beta-minus decay. The paper details the stable and unstable isotopes involved, including F-18, and their applications in medical diagnostics. Adapted from the work of Jens Langner, this study offers a comprehensive look at the technology and science underpinning PET imaging.
