New ultrasound technique could help surgeons see brain activity in real time
NCT ID NCT02656407
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new, highly sensitive ultrasound technique to map brain activity during surgery in 23 adults with brain tumors or lesions. The method aims to provide real-time images of blood flow changes linked to brain function, without needing contrast agents. Researchers compared it to standard methods like cortical stimulation mapping and functional MRI to see if it could accurately identify active brain areas.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ultrasound device (Aixplorer)
What this could lead to
If successful, this could provide a cheaper, real-time way to map brain function during surgery, potentially improving surgical precision.
What could go wrong
This is a small, early-stage study (23 people) testing a new imaging method. It may not prove better than existing techniques, and results may not apply to all patients.
