A novel graph-based AI system, RSA-KG, significantly improves clinical decision support for diagnosing recurrent spontaneous abortion (RSA) by integrating multimodal clinical data and expert guidelines.
Key Details
- 1RSA-KG integrates structured and unstructured clinical data, including imaging reports, lab values, and molecular biomarkers.
- 2The knowledge graph is built from five major international RSA guidelines and extensive literature using NLP and multimodal AI models.
- 3A rigorous evaluation with 3,000 clinician-validated questions showed RSA-KG-enhanced LLMs outperform naive RAG and raw models (e.g., 86.5% vs. 76.5% accuracy for DeepSeek-R1).
- 4Qualitative expert scoring from 10 clinicians confirmed higher clinical usefulness of RSA-KG outputs over standard LLMs and other medical models.
- 5Key limitations include limited biomarker recency, single-discipline expert evaluation, and need for multicenter clinical validation.
Why It Matters
RSA-KG demonstrates a state-of-the-art integration of guidelines, imaging, and clinical data via AI, highlighting pathways to more adaptable and clinically relevant decision support systems in complex diagnostic areas. Radiology-AI professionals can leverage such frameworks for robust, multimodal reasoning and model validation.
