Summary

This study tests whether a quick, routine ultrasound measurement (called the resistance index) can accurately identify people with narrowed neck arteries who have normal brain blood flow response. If it works, many patients could avoid a time-consuming, specialized test. The study will involve 77 participants with significant carotid artery narrowing or blockage.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could provide a quick, simple test to identify which patients with carotid artery narrowing need further evaluation for stroke risk.
What could go wrong: This is a small, early-stage diagnostic study (77 participants) testing a new use for an existing measure. The results may not apply to all patients or settings.
