RADAR: Enhancing Radiology Report Generation with Supplementary Knowledge Injection

Year: 2025
Type: conference-paper
Abstract: Large language models (LLMs) have demonstrated remarkable capabilities in various domains, including radiology report generation.Previous approaches have attempted to utilize multimodal LLMs for this task, enhancing their performance through the integration of domainspecific knowledge retrieval.However, these approaches often overlook the knowledge already embedded within the LLMs, leading to redundant information integration.To address this limitation, we propose RADAR, a framework for enhancing radiology report generation with supplementary knowledge injection.RADAR improves report generation by systematically leveraging both the internal knowledge of an LLM and externally retrieved information.Specifically, it first extracts the model's acquired knowledge that aligns with expert imagebased classification outputs.It then retrieves relevant supplementary knowledge to further enrich this information.Finally, by aggregating both sources, RADAR generates more accurate and informative radiology reports.Extensive experiments on MIMIC-CXR, CHEXPERT-PLUS, and IU X-RAY demonstrate that our model outperforms state-of-the-art LLMs in both language quality and clinical accuracy 1 .
