What is Explainable AI in COVID-19 Imaging?
Explainable AI in COVID-19 Imaging applies interpretability techniques like Grad-CAM, LIME, and SHAP to visualize CNN attention maps in chest radiographs for COVID-19 detection, building clinician trust.
Researchers use XAI to expose decision rationales in deep learning models for COVID-19 radiology, addressing black-box limitations. DeGrave et al. (2021) demonstrated that AI models rely on shortcuts rather than signals, using explainability to reveal this in chest X-rays. Over 400 papers explore these methods since 2020, with techniques validated across datasets.
Why It Matters
XAI enables clinicians to validate AI predictions against radiological features, accelerating FDA approvals for COVID-19 tools. DeGrave et al. (2021) showed models exploit hospital logos instead of lung pathology, guiding robust model redesign. In practice, SHAP visualizations in imaging pipelines support real-time triage in overwhelmed ICUs, as noted in reviews by Al Kuwaiti et al. (2023) on AI diagnostics. This trust gap closure boosts adoption in 21st-century hospitals (Maleki Varnosfaderani and Forouzanfar, 2024).
Key Research Challenges
Shortcut Learning Detection
AI models detect COVID-19 via non-clinical shortcuts like imaging artifacts. DeGrave et al. (2021) used explainability to uncover reliance on hospital watermarks over lung opacities. This reduces generalization across datasets.
Faithful Explanation Generation
XAI methods like Grad-CAM produce misleading heatmaps not reflecting model decisions. Khan et al. (2023) highlight fidelity issues in healthcare AI explanations. Validation requires perturbation tests for reliability.
Clinical Interpretability Gap
Technical visualizations confuse radiologists without domain adaptation. Coelho (2023) notes poor translation from AI heatmaps to clinical reasoning. User studies are needed to align explanations with physician workflows.
