AI Stroke Imaging Tool Reduces Median CT-to-Groin Puncture Time from 47 to 35 Minutes

Adjusted median CT-to-groin time fell from 47 to 35 mins and CT-to-perfusion map time from 7 to 6 mins after AI tool implementation; benefit concentrated at primary stroke centres; clinical outcomes unchanged.

• In 970 EVT patients, adjusted median NCCT-to-groin time dropped from 47 to 35 min (established period).
• NCCT-to-perfusion map availability reduced from 7 to 6 min.
• Improvements driven by primary stroke centres; no significant change in early neurologic improvement or 90-day functional outcomes.
