Abstract
The state of the art and future perspectives of new radionuclides in Nuclear Medicine continue to evolve, driven by the development of isotopes with innovative applications in theragnostics.
In this second part of the continuing education series, the clinical and therapeutic applications of terbium, actinium, and bismuth are analyzed in depth. The use of the 4 terbium isotopes (terbium-149, terbium-152, terbium-155, and terbium-161) is described, offering a versatile system for both diagnosis and treatment due to their chemical similarity to lutetium-177, along with the challenges related to their production and availability. Additionally, actinium-225, a powerful alpha-emitting radionuclide, is reviewed for its growing role in targeted alpha therapy, particularly in prostate cancer and neuroendocrine tumors. Finally, bismuth-213, derived from actinium-225, is analyzed for its short half-life, making it a viable option for localized and selective therapies.
Despite technical and production challenges, these radionuclides are driving the evolution of precision medicine, expanding therapeutic and diagnostic possibilities in Nuclear Medicine.
期刊介绍:
The Revista Española de Medicina Nuclear e Imagen Molecular (Spanish Journal of Nuclear Medicine and Molecular Imaging), was founded in 1982, and is the official journal of the Spanish Society of Nuclear Medicine and Molecular Imaging, which has more than 700 members.
The Journal, which publishes 6 regular issues per year, has the promotion of research and continuing education in all fields of Nuclear Medicine as its main aim. For this, its principal sections are Originals, Clinical Notes, Images of Interest, and Special Collaboration articles.
