Optical brain monitoring to detect large vessel blockage in stroke patients
Official title: Optical Cerebral Hemodynamic Monitoring for the Detection of Large Vessel Occlusion
Funded at University of Pennsylvania · NIH-11385970 · Data updated 2026-11-12
A lightweight, non-invasive optical test helps identify large vessel blockage in patients with suspected stroke so they can be routed quickly to the right hospital.

Who could benefit from this research
✓Could help
People experiencing acute stroke symptoms where LVO is suspected and prehospital or ED evaluation is feasible.
✕Less likely to help
Patients without large vessel occlusion or without access to the device due to logistical constraints may not benefit.
What this research studies
This grant develops an inexpensive, portable optical device that measures cerebral blood flow to help detect large vessel occlusion in acute stroke patients before hospital arrival. The approach uses fast, high-quality signal data and a neural network to interpret waveform patterns, aiming to improve prehospital triage. By enabling EMS and emergency departments to identify LVO more accurately, this work could shorten time to definitive therapy and improve outcomes for stroke patients.
Why it matters
Potential benefit: Could speed proper routing to thrombectomy-capable centers and shorten time to treatment for patients with large vessel occlusion.
How similar studies have gone: Preliminary work shows promise; this project builds on a validated optical CBF waveform method and applies deep learning for LVO detection.
