摘要:

获得胸部X光等常见检查的自动初步读取报告将加快临床工作流程并提高医院的运营效率。然而,当前自动化方法生成的报告的质量在临床上尚不可接受,因为它们不能确保正确检测广泛的放射学发现,也不能准确地描述它们的偏侧性、解剖位置、严重程度等。我们提出了一个领域感知的自动胸部X射线放射学报告生成算法,学习精细,对图像中的发现进行粒度化描述,并使用其出现模式从大型报告数据库中检索和自定义类似报告。我们还开发了一种自动标记算法,用于将这些描述符分配给图像,并构建了一个新颖的深度学习网络,可以识别发现的粗粒度和细粒度描述。由此产生的报告生成算法显着优于使用既定的评分指标的最新技术水平。

英文摘要:

Obtaining automated preliminary read reports for common exams such as chest X-rays will expedite clinical workflows and improve operational efficiencies in hospitals. However, the quality of reports generated by current automated approaches is not yet clinically acceptable as they cannot ensure the correct detection of a broad spectrum of radiographic findings nor describe them accurately in terms of laterality, anatomical location, severity, etc. In this work, we present a domain-aware automatic chest X-ray radiology report generation algorithm that learns fine-grained description of findings from images and uses their pattern of occurrences to retrieve and customize similar reports from a large report database. We also develop an automatic labeling algorithm for assigning such descriptors to images and build a novel deep learning network that recognizes both coarse and fine-grained descriptions of findings. The resulting report generation algorithm significantly outperforms the state of the art using established score metrics.
