Multicenter Validation of an AI-Based CTA Tool for Anterior Circulation Large Vessel Occlusion Detection.

AI Decision Support for Emergency Triage of Large Vessel Occlusion Using Noncontrast Computed Tomography: Systematic Review and Bayesian Diagnostic Test Accuracy Network Meta-Analysis.

Findings support prospective evaluation of NCCT-based AI as a bounded human-in-the-loop prompt for expert review, computed tomography angiography prioritization, tele-stroke consultation, or transfer discussion.

Prospective Shadow-Mode Evaluation of an Artificial Intelligence Tool for Intracranial Aneurysm Detection on CT Angiography: Incremental Yield and Operational Impact.

OBJECTIVE To evaluate the operational performance of an FDA-cleared artificial intelligence (AI) algorithm for brain CT angiography (CTA) aneurysm detection and the incremental value of combining AI with radiologists. METHODS Prospective shadow-mode study of consecutive brain CTAs (November 7, 2023, to December 19, 2...

Size and location of intracranial hemorrhage in acute stroke presentations: correlation with baseline NIHSS and relevance to direct-to-angiography workflows

Background and purpose Direct-to-angiography (DTA) workflows for suspected large vessel occlusion stroke reduce treatment delays by bypassing emergency-department imaging, but their safety depends on excluding intracranial hemorrhage (ICH) on flat-panel detector CT (FDCT), where posterior fossa visualization is limited...

The Added Value of Vessel Wall MRI Over CTA for Differentiating Large-Artery Atherosclerotic and Cardioembolic Stroke in the Anterior and Posterior Circulations.

BACKGROUND AND PURPOSE Differentiation between stroke etiologies is essential for secondary prevention; however, etiologic classification remains challenging in many ischemic strokes. We evaluated whether magnetic resonance vessel wall imaging (VWI) plaque markers improve computed tomography angiography (CTA)-based dif...

CTA-based imaging parameters for differentiating tandem from isolated internal carotid artery occlusion: development of a multivariable prediction model.

Perfusion imaging-guided risk stratification and endovascular decision-making in low-NIHSS large-vessel occlusion stroke: a systematic review and exploratory meta-analysis

A systematic review and exploratory meta-analysis of studies evaluating perfusion or hemodynamic imaging in adults with low-NIHSS LVO stroke found large Tmax-defined hypoperfusion volumes, larger perfusion lesion volumes, and impaired hemodynamic reserve were associated with early neurological deterioration or poor fun...
