What this research studies

This project develops tiny silver-telluride nanoparticles that act as a contrast agent for dual-energy (contrast-enhanced) mammography. Researchers will compare the new nanoparticles with current iodine-based contrast agents in lab and imaging experiments to improve tumor-to-background signal and reduce allergic reactions and false positives. Early work may include lab and animal studies followed by imaging at clinical sites to see how the agent performs in breast screening. The aim is to create a safer, more reliable contrast option that helps detect cancers earlier in women with dense breasts.

Who could benefit from this research

Good fit: Ideal candidates would be women with dense breast tissue who are undergoing supplemental breast screening or are at higher risk for breast cancer.

Not a fit: People without dense breasts or those who cannot receive contrast agents (for example, due to specific allergies or other contraindications) may not benefit from this approach.

Why it matters

Potential benefit: If successful, this could make mammogram-based screening more accurate for women with dense breasts, helping find cancers earlier and reducing unnecessary follow-up tests.

How similar studies have performed: Contrast-enhanced mammography using iodine is already used clinically, but using silver-telluride nanoparticles is a novel approach with limited prior human testing.
