Eyes Tell the Truth: GazeVal highlights the shortcomings of Generative AI in Medical Imaging

Current evaluations for synthetic medical imaging data predominantly rely on computational metrics that fail to align with human expert recognition. This leads to synthetic images that may appear realistic numerically but lack clinical authenticity, posing significant challenges in ensuring the reliability and effectiveness of AI-driven medical tools. To address this gap, we will talk about a practical framework (called GazeVal) that synergizes expert eye-tracking data with direct radiological evaluations to assess the quality of synthetic medical images. GazeVal leverages gaze patterns of radiologists as they provide a deeper understanding of how experts perceive and interact with synthetic data in different tasks (ie, diagnostic or Turing tests). We will also give some initial results on evaluation of synthetic medical scans. Experiments with sixteen radiologists revealed that 96.6% of the generated images (by the most recent state-of-the-art AI algorithm) were identified as fake, demonstrating the limitations of generative AI in producing clinically accurate images.
