Could new imaging probes spot breast cancer more accurately?
NCT ID NCT06715826
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two new radioactive imaging probes that target specific markers on breast cancer cells. Researchers will use PET/CT scans to see how well these probes find tumors and their spread in 200 women with breast cancer. The goal is to improve diagnosis and help guide treatment decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- [18F]F-RESCA-RT4 and [18F]F-RESCA-RB14 (radioactive imaging probes)
- What this could lead to
- If successful, these probes could provide a more accurate way to detect breast cancer and its spread, helping doctors choose the right treatments.
- What could go wrong
- This is an early-phase study with only 200 participants, so results may not apply to all patients. The probes are experimental and may not prove better than current imaging methods.
