Assessing Population-Based Radiological Brain Health in Stroke Epidemiology (APRISE): Rationale and Design.

Introduction: Approximately 20% of strokes in the United States are preceded by either a stroke or transient ischemic attack (TIA). Determining which stroke patients are at higher risk for recurrence allows for individualized, aggressive secondary stroke prevention. A comprehensive clinical decision tool, considering the full spectrum of radiological brain health" including small vessel disease parameters, is currently lacking.

Circle of Willis Variants and Their Association with Outcome after Successful Revascularization of Anterior Large Vessel Occlusion.

Background And Purpose: Leptomeningeal collaterals have been associated with better outcomes in large-vessel stroke, but little is known about how the Circle of Willis (CoW) collaterals affect stroke outcomes. We aimed to determine the relationship between three anatomically distinct CoW subtypes and 90-day outcomes in acute ischemic stroke patients after successful revascularization via endovascular thrombectomy (EVT).

Materials And Methods: We performed a retrospective analysis of patients treated with successful EVT for large-vessel occlusion at a comprehensive stroke center between May 2016 and November 2023.

Performance of Automated Algorithm in Large and Medium Vessel Occlusion Detection: A Real-World Experience.

Background And Purpose: Fast, accurate detection of large (LVO) and medium vessel occlusion (MeVO) is critical for triage and management of acute ischemic stroke. Multiple artificial intelligence (AI)-based software programs are available commercially for automated detection and rapid prioritization of LVO. However, their ability, strengths, and limitations for detection of acute vessel occlusion in the context of expanding indications for mechanical thrombectomy are not entirely understood.
