Abstract

fetched live from OpenAlex

Acute stroke imaging is paramount for quick diagnostic decisions using imaging modalities, including computerized tomography and magnetic resonance imaging. These modalities provide valuable information to determine the disease etiology and course of action. "Time is brain," and as such, there are unique challenges regarding acute stroke imaging, including acute decision making, limited resource availability, and compromised image quality. Artificial intelligence (AI) tools may provide support for acute stroke imaging in clinical care settings and have the potential to mitigate many of these challenges. This paper investigates the role of AI in acute stroke imaging in research and industry, including reviewing 39 papers published between 2022 and 2025 that investigated the development and application of tools specific to interventional radiology and stroke and examined their tools' efficacy and the studies' consideration of data privacy, reproducibility, and practical usability. We also investigated four commercially available AI tools available for clinical use, focusing on their primary objectives, strengths, and limitations. We found that while AI tools demonstrate the potential for improving time-to-treatment and diagnostic accuracy, there are key limitations related to low reproducibility, the development of impractical tools, and minimal documentation about AI development and employment.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
