New scan could spot hidden stroke risk in blocked arteries
NCT ID NCT05838547
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether a new type of PET-MR scan can help predict stroke risk in people with significant narrowing of the carotid artery (the main artery in the neck) who have not yet had symptoms. Researchers will give participants an injection of a radioactive tracer and take images of their arteries. They will then follow participants for up to 18 months to see who has a stroke or needs treatment, to see if the scan signal correlates with risk.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
64Cu-25%-CANF-Comb (a radioactive tracer for PET imaging)
What this could lead to
If successful, this could lead to a better way to identify which patients with carotid artery narrowing are at highest risk for stroke, helping guide treatment decisions.
What could go wrong
This is an early observational study, not a treatment trial. The imaging technique may not prove accurate enough to predict risk, and results may not apply to all patients.
