PET-MR scan study for narrowing in the carotid artery
Part of Brain & nervous system, Heart & circulation clinical trials.
This study tests how well a special PET-MR scan can help evaluate carotid artery plaque in people who have significant narrowing but no symptoms. It may help researchers better understand disease activity to guide treatment decisions like medication alone or medication plus surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You do not currently have stroke-like symptoms, but your carotid imaging showed at least 60% narrowing.
- Your doctor has already decided on a plan: medication only, or medication plus carotid endarterectomy surgery.
- You must be able to lie flat (on your back) for up to 60 minutes during the PET-MR scan.
- You have not had carotid endarterectomy or a carotid stent on the same side before.
- You cannot have had a TIA (mini-stroke) or stroke in the last 6 months, and you must be able to give consent.
- You can safely have an MRI (for example, no implanted metal devices that are not MRI-safe, and you’re not too claustrophobic).
- If you can get pregnant, you must have a negative pregnancy test right before the scan; the study also excludes being pregnant or breastfeeding.

This Phase 1 study tests whether a special PET scan can detect a specific inflammation signal (CCR2) in atherosclerosis—fatty plaque buildup in blood vessels. It may help future doctors better see which plaques are more inflamed and potentially more dangerous.
This trial tests a stent procedure to open a severely blocked carotid artery in people who have not had a stroke or mini-stroke from that blockage recently. It aims to see if the procedure is safe and effective for preventing future strokes.
This trial uses special PET/MR scans to look at fatty buildup in your neck arteries to see which ones might be dangerous. It could help doctors better understand your stroke risk and choose the right treatment.
This study tests whether a special type of PET/MRI scan can help doctors see inflammation in the carotid artery after a stroke or mini-stroke. By using a radioactive tracer, the scan may identify which patients have dangerous plaque buildup that could lead to another stroke.
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 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.
