Radionuclides for Targeted Therapy: Physical Properties

Area of Science:

• Nuclear medicine
• Radiopharmaceutical therapy
• Medical physics

Background:

• Targeted radionuclide therapy is expanding, with 72 radionuclides identified for use.
• Understanding radionuclide properties is crucial for optimizing therapeutic efficacy and safety.

Purpose of the Study:

• To review the physical characteristics of radionuclides relevant to targeted radionuclide therapy.
• To discuss how these properties can be optimized for specific therapeutic applications.

Main Methods:

• Literature search of PubMed for radionuclides used in targeted radionuclide therapy.
• Analysis of physical characteristics including linear energy transfer, relative biological effectiveness, range, half-life, and imaging properties.

Main Results:

• Radionuclide properties vary significantly, impacting suitability for different targets.
• Properties like radiation range and imaging capabilities present trade-offs between efficacy and safety.
• Optimizing radionuclide selection requires balancing these diverse physical characteristics.

Conclusions:

• No single radionuclide is universally ideal; selection depends on the specific target and therapeutic goals.
• The 72 investigated radionuclides, and others, offer a wide range of properties for tailored radionuclide therapy.
