科学领域:

  • 人工智能在医学中的应用
  • 放射学 信息学 信息学

背景情况:

  • 放射学报告的印象至关重要,但可能是主观的.
  • 需要自动化方法来产生一致的印象.

研究的目的:

  • 微调和评估一个开源的大型语言模型 (LLM) 用于自动生成放射学报告印象.
  • 评估LLM在不同成像模式和医疗机构的表现.

主要方法:

  • 一项回顾性研究利用了来自两个医院的CT,US和MRI报告的大数据集.
  • 用于自动评估的回忆导向的基底研究对凝结评估 (ROUGE) 评分被使用.
  • 一个读者研究与五个子专业放射科医生评估临床准确性,语法和风格.

主要成果:

  • 该LLM在各种模式中取得了显著的ROUGE-L分数,这表明与人写的印象有很大的重叠.
  • 读者研究表明,在临床准确性 (3.56/4),语法准确性 (3.92/4),和风格质量 (3.37/4) 中,LLM印象得分很高.
  • 在急性发现和较短的印象中,LLM的表现最高,在外部验证上略有下降.

结论:

  • 一个微调的开源LLM可以产生放射学报告印象,具有可接受的临床准确性,语法和风格.
  • LLM显示出绘制印象的潜力,有助于简化放射科医生的工作流程.
