Distal vessel occlusions often missed on CTA; Tmax maps and AI may help

Computed tomography angiography (CTA) often fails to detect distal medium vessel occlusions (DMVOs), but time-to-maximum (Tmax) perfusion maps show significantly higher sensitivity, and emerging AI tools may aid diagnosis.

• Endovascular thrombectomy for DMVOs remains debated and requires further device refinement.
• Current evidence is limited to single-center studies; multicenter trials are needed to establish standardized protocols.
