摘要:
放射学报告中“Impression(印象)”部分的人工撰写是导致放射科医生倦怠的主要原因。为应对这一挑战,我们提出一种由粗到细的框架,利用开源大型语言模型(LLM),根据临床发现自动生成并个性化印象。该系统首先生成印象草稿,随后使用机器学习和基于人类反馈的强化学习(RLHF)对其进行优化,以契合不同放射科医生的风格,同时确保事实准确性。我们在来自芝加哥大学医学中心的大规模报告数据集上微调了 LLaMA 和 Mistral 模型。我们的方法旨在显著减少行政工作量、提高报告效率,同时保持高标准的临床精确性。
英文摘要:
The manual creation of the "Impression" section in radiology reports is a primary driver of radiologist burnout. To address this challenge, we propose a coarse-to-fine framework that leverages open-source large language models (LLMs) to automatically generate and personalize impressions from clinical findings. The system first produces a draft impression and then refines it using machine learning and reinforcement learning from human feedback (RLHF) to align with individual radiologists' styles while ensuring factual accuracy. We fine-tune LLaMA and Mistral models on a large dataset of reports from the University of Chicago Medicine. Our approach is designed to significantly reduce administrative workload and improve reporting efficiency while maintaining high standards of clinical precision.
