Introduction Given the robust evidence supporting thrombectomy in the treatment of acute stroke, accurate prehospital triage to thrombectomy capable centers has become an imperative. Here we present the results of a large scale clinical trial evaluating a non-invasive, hand-held device capable of identifying large vessel occlusion and other severe brain pathologies in neurologically compromised patients.

Methods We are currently completing a multicenter derivation study of up to 158 adult patients presenting to the hospital with atraumatic severe brain pathology who are evaluated with this new technology. The presence or absence of LVO and other severe brain pathology was confirmed on neuroimaging including CT, MR, and/or angiography.

Results The results of this study will be complete by early-June and are planned to be presented.

Conclusion We will present the conclusions of a large scale clinical trial evaluating a new hand-held non-invasive brain scanning device that has the potential to transform pre-hospital triage of patients with neurologic impairment.
