    AI assistance significantly improved diagnostic performance for detecting acute ischemic stroke lesions on diffusion-weighted MRI.

  • 2

    The study included 3,986 patients, focusing on 250 challenging cases for a multi-reader performance evaluation.

  • 3

    AI achieved a sensitivity of 96.0% and identified 79.6% of false-negative stroke cases from clinical reports.

  • 4

    AI-assisted reading improved the area under the curve from 0.85 to 0.93 and pooled sensitivity from 74.6% to 90.6%.

  • 5

    Reader confidence increased with AI support, particularly in challenging cases, despite a slight decrease in specificity.
