NCT ID NCT07187895
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared a newer PET heart scan (using XTR004) with a standard SPECT scan to see which gives doctors more confidence in diagnosing borderline blocked arteries. It involved 17 adults with suspected stable heart disease and 30-90% blockages seen on a prior CT scan. The goal was to measure how often each method gave a clear diagnosis for each artery.
