Summary
Alpha-emitting radiopharmaceuticals offer advantages over beta-emitters for personalized theranostics. This article explores the potential of lead-212 as a theranostic agent for improved cancer treatment with reduced toxicity.
Area of Science:
- Nuclear medicine and oncology
Background:
- Theranostics combines diagnostic and therapeutic nuclear medicine for personalized treatment.
- Current theranostics primarily utilize beta-emitting radiopharmaceuticals.
- Alpha-emitting radiopharmaceuticals present potential advantages due to their physical characteristics.
Purpose of the Study:
- To review the potential of alpha-emitters in theranostics.
- To focus on lead-212 (212Pb) as a theranostic agent.
Main Methods:
- Review of existing literature on alpha-emitters and theranostics.
- Analysis of the properties of lead-212 for therapeutic applications.
Main Results:
- Alpha-emitters offer greater cell-killing potential compared to beta-emitters.
- Alpha-emitters have a shorter range, potentially reducing toxicity to surrounding healthy tissues.
- Lead-212 possesses suitable decay properties for theranostic applications.
Conclusions:
- Lead-212 shows significant promise as a theranostic agent.
- Further research and clinical trials are warranted to explore the full potential of 212Pb-based theranostics.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
