MRI study to assess stroke risk from carotid narrowing
Part of Brain & nervous system, Heart & circulation clinical trials.
This study looks at how dangerous carotid artery narrowing (blood vessels in the neck that supply the brain) might be, using CT and MRI information. It may help doctors better judge stroke risk for people with mild, moderate, or severe narrowing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a CT scan (CTA) showing carotid artery narrowing in one of these ranges: under 30%, 30–69%, or 70% or more.
- You do not have dementia, and your thinking test (MMSE) score is 21 or higher.
- You have NOT had past brain/nerve symptoms caused by carotid narrowing or a “mini-stroke” (transient ischemic attack).
- You do not have other major brain/large-vessel problems (like brain tumors, infections/inflammation, injuries, or certain vessel complications).
- You can safely have an MRI scan (no MRI safety contraindications).
- You have not recently taken psychoactive drugs or hormone medicines.

This study uses MRI scans to build a risk prediction model for stroke and other cerebrovascular events in people with carotid artery stenosis (narrowing of the neck arteries). By participating, you help doctors better understand who is at highest risk, which may lead to more personalized treatment.
This study uses advanced PET/MRI scans to measure blood flow and sugar use in the brain. It is for people who have had a stroke or mini-stroke in the past year due to a severely narrowed carotid artery.
This study uses a special MRI technique to take detailed pictures of the walls of narrowed arteries in the brain or neck. It aims to better understand the plaques that cause the narrowing, which may help guide treatment. If you have moderate to severe narrowing in these arteries, this imaging could provide important information for your care.
This study tests a new imaging agent that may help doctors see how blood flows in the brain after a stroke or mini-stroke. It could help guide treatment for people with severe narrowing in one of the main arteries in the neck or head.
This study looks at an approach to better plan treatment for people with significant narrowing of the carotid artery (the main artery to the brain). It may help doctors choose safer, more effective care after surgery.
This trial studies how blood flow and brain function change after a carotid artery revascularization procedure (opening a narrowed carotid artery). It may help doctors understand what to expect after treatment, especially in people with significant artery narrowing.
