Heart scans with 100x less radiation? new study tests safer imaging
NCT ID NCT07284576
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new PET heart scan that uses 100 times less radiation than current methods. Researchers will scan 200 adults with known or suspected heart artery disease to see if the ultra-low dose still produces clear images. The goal is to make heart imaging safer while keeping it effective for detecting blockages or damage.
