MedFILIP: Medical Fine-Grained Language-Image Pre-Training
IEEE Journal of Biomedical and Health Informatics
|March 3, 2025
Summary
MedFILIP enhances medical vision-language pretraining (VLP) for accurate disease diagnosis. This model improves image-text alignment and classification accuracy, aiding medical image analysis.
Area of Science:
- Artificial Intelligence
- Medical Imaging Analysis
- Computer Vision
Background:
- Medical vision-language pretraining (VLP) is vital for medical image analysis.
- Current VLP models struggle with accurate image-disease associations, impacting diagnostic accuracy.
Purpose of the Study:
- To introduce MedFILIP, a fine-grained VLP model designed to improve medical image analysis.
- To enhance the characterization of associations between medical images and diseases.
Main Methods:
- Utilized a large language model-based information extractor for comprehensive disease detail extraction.
- Developed a knowledge injector to establish relationships between visual attributes and categories.
- Implemented a semantic similarity matrix with fine-grained annotations for improved image-text alignment.
Main Results:
- Achieved state-of-the-art performance on single-label, multi-label, and fine-grained classification tasks.
- Demonstrated significant improvements in classification accuracy, with a maximum increase of 6.69%.
- Validated on diverse datasets including RSNA-Pneumonia, NIH ChestX-ray14, VinBigData, and COVID-19.
Conclusions:
- MedFILIP effectively addresses limitations in current medical VLP models.
- The model shows strong potential for advancing accurate and comprehensive medical image analysis and diagnosis.
