Automated detection of hyperdense artery sign on non-contrast CT for rapid identification of large vessel occlusion: a multicenter validation study

PurposeComputed tomography angiography (CTA) is the gold standard for detecting large vessel occlusion, but its acquisition and reconstruction delay time-critical workflow. The hyperdense artery sign (HAS) on non-contrast CT (NCCT) offers an immediate, albeit subtle, marker. We developed a fully aut...
