This study introduces a new framework combining radiomics and contrastive learning for pneumonia detection in chest X-rays. The model improves diagnostic accuracy and interpretability, addressing challenges in manual reading and deep learning opacity.
Area of Science:
- Medical Imaging Analysis
- Artificial Intelligence in Radiology
Background:
- Chest X-rays are crucial for noninvasive diagnosis, but manual interpretation leads to radiologist burnout and diagnostic delays.
- Radiomics offers quantitative feature extraction from medical images, aiding diagnosis before the deep learning era.
- Deep learning models for chest X-ray diagnosis lack transparency and explainability.
Purpose of the Study:
- To develop a novel framework for pneumonia detection in chest X-rays.
- To enhance the interpretability of AI models in medical imaging.
- To combine radiomics features with contrastive learning for improved diagnostic performance.
Main Methods:
- A novel framework integrating radiomics features with contrastive learning was proposed.
- The model was trained and evaluated on the RSNA Pneumonia Detection Challenge dataset.
- Performance was compared against several state-of-the-art models.
Main Results:
- The proposed model achieved superior results compared to existing state-of-the-art methods.
- The model demonstrated a significant improvement in F1-score, exceeding 10%.
- Enhanced model interpretability was achieved.
Conclusions:
- The framework effectively detects pneumonia in chest X-rays.
- Combining radiomics and contrastive learning offers a promising approach for interpretable AI in medical diagnostics.
- This method addresses the explainability gap in deep learning for chest X-ray analysis.
