Multimodal artificial intelligence models for radiology

Area of Science:

• Medical Artificial Intelligence
• Radiology Informatics

Background:

• Clinical decision-making integrates multiple data sources, a capability often lacking in current medical AI.
• Existing AI models struggle to incorporate diverse data modalities, limiting their real-world applicability.

Purpose of the Study:

• To provide a comprehensive overview of multimodal AI research in radiology.
• To analyze various fusion modeling approaches, including traditional and vision-language models.
• To highlight the comparative advantages, disadvantages, and ethical considerations of these AI methods.

Main Methods:

• Review of existing literature on multimodal AI in radiology.
• Categorization and analysis of different fusion techniques.
• Discussion of comparative merits and drawbacks.

Main Results:

• Identified a range of multimodal AI approaches, from traditional fusion to advanced vision-language models.
• Analyzed the strengths and weaknesses of each method for radiological applications.
• Emphasized the importance of data quality, computational resources, and clinical context in selecting fusion methods.

Conclusions:

• Multimodal AI holds significant potential to bridge the gap between AI capabilities and clinical decision-making in radiology.
• Careful consideration of data, resources, and ethical implications is crucial for successful implementation.
• Future research should focus on developing robust fusion models tailored to specific clinical needs.
