摘要:

放射学报告的印象部分以自然语言总结了重要的放射学发现,并在将这些发现传达给医生方面发挥了核心作用。然而,通过总结发现来生成印象的过程对于放射科医生来说是耗时的并且容易出错。我们建议使用神经序列到序列学习来自动生成放射学印象。我们还为此任务提出了一个定制的神经模型,该模型学习对学习背景信息进行编码,并使用这些信息来指导解码过程。在从实际医院研究中收集的放射学报告的大型数据集上,我们的模型在ROUGE指标下优于现有的非神经和神经基线。在一项盲法实验中,一位经过认证的放射科医生表示,67%的采样系统摘要至少与相应的人类书面摘要一样好,这表明了显著的临床有效性。据我们所知,我们的工作是这方面的第一次尝试。

英文摘要:

The Impression section of a radiology report summarizes crucial radiology findings in natural language and plays a central role in communicating these findings to physicians. However, the process of generating impressions by summarizing findings is time-consuming for radiologists and prone to errors. We propose to automate the generation of radiology impressions with neural sequence-to-sequence learning. We further propose a customized neural model for this task which learns to encode the study background information and use this information to guide the decoding process. On a large dataset of radiology reports collected from actual hospital studies, our model outperforms existing non-neural and neural baselines under the ROUGE metrics. In a blind experiment, a board-certified radiologist indicated that 67% of sampled system summaries are at least as good as the corresponding human-written summaries, suggesting significant clinical validity. To our knowledge our work represents the first attempt in this direction.
