Improving detection of clot signals in brain ultrasound
Part of Brain & nervous system, Heart & circulation clinical trials.
This study focuses on improving how doctors classify tiny signals (called microembolic signals) from the brain, which can help detect stroke risk. Your recorded signals—if from a solid source, like a clot—will be reviewed by experts to develop better computer tools.
Summary written for real people, not researchers, by Clin2.
Who can take part
- The signal (microembolic signal or MES) must be from a solid source, like a clot or plaque
- You must be 18 years or older
- The signal must come from the middle cerebral artery (M1 segment)
- The 20-second recording must be clear and have the event marked
- No recent use of ultrasound contrast agents (like agitated saline) in the last 24 hours
- No mechanical heart valve, recent heart surgery, endovascular procedure, or severe trauma

Other trials that look related to this one.
This trial tests a new type of brain scanner (similar to a helmet) that looks for bleeding in the brain without radiation. It is for people who have had stroke-like symptoms in the last 24 hours and have not yet received treatment.
This study compares two types of clot/brain-bleeding risk imaging scans to see which better predicts recovery in people with ischemic stroke. If you qualify and get the right timing and scan results, the trial may help doctors choose the best way to predict your prognosis.
This trial tests whether a special AI software can help doctors speed up the process of referring patients with acute stroke for a procedure that removes a blood clot (thrombectomy). If you have stroke symptoms and a recent CT scan, the AI may help identify if you could benefit from this treatment.
This trial uses an AI-assisted ultrasound to quickly detect brain bleeding in people with acute stroke. It may help speed up diagnosis and treatment.
This trial looks at how blood flow and brain activity change in the first days after a stroke caused by a large blockage in the front part of the brain. It tests if certain patterns can help predict recovery after a procedure to remove the clot.
This study looks at heart ultrasound pictures and heart-rhythm recordings to predict who may develop atrial fibrillation (AF) after a stroke or TIA. If you qualify, your results may help doctors better spot people at higher risk earlier.
