Researchers prospectively collected the COVID-BLUeS dataset, the largest standardized public lung ultrasound dataset for COVID-19, to rigorously evaluate AI models for diagnosis and severity assessment. The study found that while AI models outperformed human experts on this challenging dataset, clinical variables alone demonstrated higher predictive accuracy (84%) than image-only LUS models, highlighting the importance of multimodal data integration and realistic performance evaluation.
Key insights
- Many reported high performance metrics for AI in LUS were likely overestimations resulting from flawed data splitting, where frame-level splitting can inflate accuracy (e.g., to 98% on the COVID-BLUeS dataset).
- Clinical variables and complete blood count data alone provided strong predictive power for COVID-19 diagnosis (up to 84% accuracy), often surpassing the performance of LUS image-only AI models.
- AI models, when rigorously evaluated, consistently outperformed human experts in COVID-19 detection (best AI at 79% image-only, 83% multimodal, vs. human experts at 65%) on the challenging COVID-BLUeS dataset.
