    摘要:

    影像报告与数据系统(RADS)是美国放射学会(ACR)旨在降低影像判读主观性、提升一致性的结构化风险分层框架。虽已广泛应用,但在真实世界实践中仍面临评分一致性受限、特征量化不足及跨中心可重复性差等方法学挑战。近年来,人工智能(AI)尤其是大语言模型(LLM)的发展为解决上述局限提供了新路径。本文系统梳理了主要RADS体系的结构特征及实践局限,综述了AI在病灶识别、风险再分层及流程规范化等方面的实证进展。现有证据显示,AI更适宜作为RADS的“增强层”,以提升其客观性与重复性。文章重点探讨了LLM在语义理解、自动推理及质控中的潜力,并从监管视角展望了人机协作的演进方向。该趋势对推动我国影像诊断同质化、提升基层诊疗水平及构建智能化监管体系具有重要指导意义。

    Abstract:

    The Reporting and Data Systems (RADS), established by the American College of Radiology (ACR), serve as structured risk-stratification frameworks designed to mitigate subjectivity and enhance consistency in radiological interpretation. Despite their widespread adoption, RADS still face methodological challenges in real-world practice, including limited inter-observer consistency, insufficient feature quantification, and suboptimal cross-center reproducibility. In recent years, the evolution of Artificial Intelligence (AI), particularly Large Language Models (LLMs), has offered novel pathways to address these limitations. This paper systematically reviews the structural characteristics and practical constraints of major RADS frameworks and synthesizes empirical progress regarding AI in lesion identification, risk re-stratification, and workflow standardization. Current evidence suggests that AI is best positioned as an "augmentative layer" for RADS to bolster objectivity and reproducibility. Furthermore, this article explores the potential of LLMs in semantic understanding, automated reasoning, and quality control, while projecting the evolution of human-computer collaboration from a regulatory perspective. This trend holds significant implications for promoting the homogenization of diagnostic imaging, empowering primary healthcare services, and establishing intelligent regulatory systems in China.
