智能体AI生成放射学论文播客摘要的准确性评估
本研究评估了自定义智能体AI流水线（P5）与通用商业工具（Google NotebookLM）生成放射学研究论文播客式摘要的质量。P5在幻觉数量、发音错误、流程中断及综合质量评分方面均显著优于NBLM。
要点
- 自定义智能体AI流水线P5生成的播客摘要幻觉显著少于通用工具NBLM。
- P5在发音准确性和流程流畅性方面表现更优，综合质量评分更高。
- 听众（放射科医生）在72.7%的比较中更偏好P5生成的音频摘要。
核心结论
- 自定义智能体AI流水线生成的放射学研究论文播客式摘要质量显著高于通用商业工具，且听众偏好度更高。
研究设计与样本
- 评估者为25名放射科医生（7名综合医师、18名专科医师）中随机抽取的4名，采用盲法评估，共完成176次评估。
- 主要结局为每集幻觉（事实错误）数量和零幻觉集百分比，次要结局包括不当表述、发音错误、流程中断数量、QAEP综合质量评分、关键结果覆盖评分及听众偏好。
- 数据分析采用广义线性混合模型。
诊断标准与关键数值
- P5平均每集幻觉数量为0.32，NBLM为0.93，P<0.001。
- P5零幻觉集百分比为71.6%（63/88），NBLM为56.8%（50/88），P=0.013。
- P5平均每集发音错误为0.11，NBLM为1.62，P<0.001。
- P5平均每集流程中断为0.19，NBLM为1.06，P<0.001。
- P5平均QAEP综合质量评分为4.62，NBLM为4.28，P<0.001。
临床应用与阅片要点
- 在科研教育与文献学习中，智能体AI流水线可作为传统全文阅读的补充工具，生成更准确的音频摘要。
- 临床医生选择播客式文献学习工具时，应优先选用具备质量控制与发音增强机制的专业流水线而非通用工具。
- 需注意所有AI生成的摘要均可能存在事实错误，关键临床决策前应核对原文。
局限性
- 原文未报告局限性内容。

OBJECTIVE: To evaluate whether a custom agentic artificial intelligence (AI) pipeline can overcome the limitations of general-purpose large language model tools, when compared with a generic commercial tool (Google NotebookLM [NBLM]), for generating podcast-style summaries of radiology research articles.
MATERIALS AND METHODS: Twenty-two PDF-format original research articles published in the April 2025 issue of Radiology were processed using our Programmable, Phoneme-Aware PDF-to-Podcast Pipeline (P5) and NBLM to generate 44 audio episodes. P5 utilizes a multi-agent workflow for script generation, quality assurance, pronunciation enhancement, and audio synthesis. Four radiologists from a pool of 25 (7 generalists and 18 specialists) were randomly assigned to evaluate each blinded audio episode, yielding 176 total evaluations. The primary outcomes were the number of hallucinations (factual errors) per episode and the percentage of hallucination-free episodes. Secondary outcomes included the number of inappropriate statements, mispronunciations, and flow disruptions; the composite quality score (Quality Assessment of Educational Podcasts [QAEP]); the key results coverage score; and overall listener preference. Data were analyzed using generalized linear mixed models.
RESULTS: The P5 method produced significantly fewer hallucinations per episode compared with NBLM (mean, 0.32 vs. 0.93; P < 0.001) and a higher proportion of hallucination-free episodes (71.6% [63/88] vs. 56.8% [50/88]; P = 0.013), consistently across generalists and specialists. P5 demonstrated significantly fewer mispronunciations (mean, 0.11 vs. 1.62; P < 0.001) and flow disruptions (mean, 0.19 vs. 1.06; P < 0.001) per episode, as well as higher mean QAEP composite scores (4.62 vs. 4.28; P < 0.001), compared with NBLM, consistently across generalists and specialists. Raters preferred P5 over NBLM in 72.7% (64/88) of comparisons (P = 0.003).
CONCLUSION: Our custom agentic AI pipeline generated podcast-style summaries of radiology research articles with significantly higher quality and greater listener preference than the generic commercial tool.
