New MRI scan could spare thousands from unnecessary stroke surgery
NCT ID NCT07556887
First seen May 01, 2026 · Last updated May 23, 2026 · Updated 6 times
Summary
This study compares a new MRI-based method (IMPROVE) against the standard approach for deciding which patients with narrowed carotid arteries need surgery or stenting. The standard method mainly looks at how narrow the artery is, while IMPROVE checks for unstable plaque that raises stroke risk. About 613 people who recently had a minor stroke or TIA will be randomly assigned to one method and followed for years to see which better prevents strokes and reduces healthcare costs.
