Radiologist Copilot: An Agentic Framework Orchestrating Specialized Tools for Reliable Radiology Reporting
- 用智能体协调多个专业工具，完成从图像定位到报告质检全流程。
- 在真实临床数据上，报告准确率显著优于现有方法。
- 适合放射科医生、AI医疗系统开发者参考使用。
在临床实践中，放射科报告是一项关键但复杂、耗时且易出错的任务，尤其针对3D医学影像。现有基于医学视觉-语言模型的自动化方法主要聚焦于孤立的报告生成，而真实世界的放射科报告远不止写作本身，还需细致的图像观察与解读、合适的模板选择以及严格的质控以符合临床标准。这一多阶段、需规划的流程远超单次推理模型的能力。为此，我们提出Radiologist Copilot，一种能够自主调度专业化工具完成完整放射科报告工作流的智能体系统。该系统支持区域图像定位与分析规划，实现详细视觉推理；采用策略性模板选择确保报告标准化；并通过质量评估与反馈驱动的迭代优化实现独立报告质控。通过整合定位、解读、模板选择、报告生成与质量控制，Radiologist Copilot提供全面且符合临床需求的报告流程。实验结果表明，其显著优于当前最优方法，在整个报告流程中有效辅助放射科医生。代码将在论文接受后开源。
原文摘要 · Abstract (English)
In clinical practice, radiology reporting is an essential yet complex, time-intensive, and error-prone task, particularly for 3D medical images. Existing automated approaches based on medical vision-language models primarily focus on isolated report generation. However, real-world radiology reporting extends far beyond report writing, which requires meticulous image observation and interpretation, appropriate template selection, and rigorous quality control to ensure adherence to clinical standards. This multi-stage, planning-intensive workflow fundamentally exceeds the capabilities of single-pass models. To bridge this gap, we propose Radiologist Copilot, an agentic system that autonomously orchestrates specialized tools to complete the entire radiology reporting workflow rather than isolated report writing. Radiologist Copilot enables region image localization and region analysis planning to support detailed visual reasoning, adopts strategic template selection for standardized report writing, and incorporates dedicated report quality control via quality assessment and feedback-driven iterative refinement. By integrating localization, interpretation, template selection, report composition, and quality control, Radiologist Copilot delivers a comprehensive and clinically aligned radiology reporting workflow. Experimental results demonstrate that it significantly outperforms state-of-the-art methods, supporting radiologists throughout the entire radiology reporting process. The code will be released upon acceptance.
