Summary

This observational study is testing whether a new digital imaging analysis can more accurately predict stroke risk in 400 adults with narrowed brain arteries (50-99% blockage). Participants undergo standard angiography, and researchers use a computer method to measure blood flow impairment. They will be followed for one year to see who has a stroke or related death, comparing the new method to traditional measurements.

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 lead to a more accurate way to identify which patients with brain artery narrowing are at highest risk of stroke, helping doctors tailor treatments.
What could go wrong: This is an observational study, not a treatment trial, so it won't directly improve outcomes. The new method may not prove more accurate than current approaches.
