论文摘要
胸部X光片是当今急诊室和重症监护病房中最常见的诊断检查。最近,许多研究人员已经开始研究大型胸部X射线数据集,以开发深度学习模型,以识别少数粗糙的发现类别,例如不透明,群众和结节。在本文中,我们专注于提取和学习用于胸部X射线图像的细粒标签。具体而言,我们通过将词汇驱动的概念提取与依赖性解析树中的短语分组相结合,从而从放射学报告中提取细粒度的标签,从而开发了一种新方法,以将修饰符与发现的结合。总共选择了457个细颗粒标签,这些标签描绘了迄今为止最大的发现,并获得了足够大的数据集,以训练专为细粒分类而设计的新的深度学习模型。我们显示的结果表明了高度准确的标签提取过程以及对细粒标签的可靠学习。据我们所知,最终的网络是第一个识别出涵盖9个修饰符的图像中发现的细粒度描述,包括横向,位置,严重性,大小和外观。
Chest radiographs are the most common diagnostic exam in emergency rooms and intensive care units today. Recently, a number of researchers have begun working on large chest X-ray datasets to develop deep learning models for recognition of a handful of coarse finding classes such as opacities, masses and nodules. In this paper, we focus on extracting and learning fine-grained labels for chest X-ray images. Specifically we develop a new method of extracting fine-grained labels from radiology reports by combining vocabulary-driven concept extraction with phrasal grouping in dependency parse trees for association of modifiers with findings. A total of 457 fine-grained labels depicting the largest spectrum of findings to date were selected and sufficiently large datasets acquired to train a new deep learning model designed for fine-grained classification. We show results that indicate a highly accurate label extraction process and a reliable learning of fine-grained labels. The resulting network, to our knowledge, is the first to recognize fine-grained descriptions of findings in images covering over nine modifiers including laterality, location, severity, size and appearance.
