MRI brain scan could prevent unnecessary stroke surgeries

NCT ID NCT07556887

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new decision-making tool called IMPROVE that uses MRI scans to detect unstable plaques in the carotid artery. The goal is to see if this method is at least as good as the current standard (which mainly looks at how narrow the artery is) for selecting which patients with a recent stroke or TIA should have surgery or stenting. About 613 participants will be randomly assigned to either the IMPROVE-based approach or usual care, and followed for several years to compare stroke rates and costs.

What this could mean

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

Active substance
IMPROVE risk model (a decision tool using MRI scans to assess stroke risk)
What this could lead to
If it works, this could help doctors decide more accurately who needs surgery to prevent a stroke, reducing strokes and unnecessary procedures.
What could go wrong
This is a mid-stage trial with 613 participants, so results may not apply to everyone. The new method might not be as effective as the standard approach, and MRI scans can be costly or unavailable.
