Comparing two imaging tests for stroke diagnosis
Part of Brain & nervous system, Heart & circulation clinical trials.
This study compares two imaging methods, magnetic resonance imaging (MRI) without contrast dye and a carotid ultrasound (Doppler), to see which one is better at finding blocked arteries in the neck that can cause strokes. The results may help doctors choose the best test for people who have had a stroke or a mini-stroke.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You had an ischemic stroke or a transient ischemic attack (TIA), also called a mini-stroke.
- Your imaging test is done between 7 and 14 days after your symptoms started.
- You are stable enough to have an MRI, and you don't have any metal implants or other reasons that would make an MRI unsafe.
- You are able to give written consent to participate.
- You have not had a hemorrhagic stroke or previous carotid artery stenting.

This study looks at using ultrasound to measure blockages in the arteries that supply the brain before a stent is placed. It aims to improve how these blockages are diagnosed.
This study looks at how the nervous system's automatic functions (like heart rate and blood pressure) change after a stroke. It uses MRI scans and blood tests to find patterns that might help doctors better understand and treat these changes.
This trial compares a non-invasive ultrasound test (Transcranial Colour Coded Duplex) to a CT angiography scan for diagnosing stroke. It may help find a simpler and safer way to assess strokes and transient ischemic attacks (mini-strokes).
This trial compares two imaging tests, MRI and CT scan, to see which is better at diagnosing a severe stroke caused by a blocked large artery in the brain. If you are eligible, you would receive one of these scans to help guide your treatment.
This study looks at new imaging markers in people with significant narrowing of the carotid artery (the main artery in the neck). It compares people who recently had a stroke from that artery with people who have no recent stroke, to better understand stroke risk and artery disease.
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.
