Automatically generated reports from medical images promise to improve the workflow of radiologists. Existing methods consider an image-to-report modeling task by directly generating a fully-fledged report from an image. However, this conflates the content of the report (e.g., findings and their attributes) with its style (e.g., format and choice of words), which can lead to clinically inaccurate reports. To address this, we propose a two-step approach for radiology report generation. First, we extract the content from an image; then, we verbalize the extracted content into a report that matches the style of a specific radiologist. For this, we leverage RadGraph -- a graph representation of reports -- together with large language models (LLMs). In our quantitative evaluations, we find that our approach leads to beneficial performance. Our human evaluation with clinical raters highlights that the AI-generated reports are indistinguishably tailored to the style of individual radiologist despite leveraging only a few examples as context.

通过从图像中提取内容，并将提取的内容转化为与特定放射科医生风格匹配的报告，我们提出了一种用于射线学报告生成的两步方法，该方法利用RadGraph和大型语言模型（LLMs）。量化评估结果证明，我们的方法带来了良好的性能。与临床评估员进行的人类评估表明，尽管只使用了几个示例作为背景信息，但AI生成的报告与个体放射科医生的风格无法区分。
