Deep learning algorithm for automatic detection of acute ischemic stroke on noncontrast brain CT
AI algorithm improves stroke diagnosis on CT scans across all provider types, especially benefiting non-radiologists in emergency settings.
A deep learning algorithm for acute ischemic stroke detection on non-contrast CT improves diagnostic accuracy across all reader types including non-radiologists (5.38% gain), with the greatest benefit in non-specialist readers — the population most likely to encounter stroke CT in emergency settings. The multi-reader crossover design provides a rigorous efficacy benchmark for clinical deployment.
