Widened arterial time-density curves of CTP may identify cardioembolic etiology in acute large-artery occlusion stroke

Key Points

• Widened arterial time-density curves indicate a possible cardioembolic origin for acute large-artery occlusion stroke.
• The presence of specific curve patterns correlated with cardioembolic events in assessed cases, showing a strong diagnostic promise.
• Analysis of CTP data from multiple patients revealed significant variations in arterial time-density curves for different stroke types.
• These findings suggest that careful examination of arterial time-density curves may enhance current diagnostic practices for strokes.
