Purpose: To develop and evaluate the accuracy of a multi-view deep learning approach to the analysis of high-resolution synthetic mammograms from digital breast tomosynthesis screening cases, and to assess the effect on accuracy of image resolution and training set size. Materials and Methods: In a retrospective study, 21,264 screening digital breast tomosynthesis (DBT) exams obtained at our institution were collected along with associated radiology reports. The 2D synthetic mammographic images from these exams, with varying resolutions and data set sizes, were used to train a multi-view deep convolutional neural network (MV-CNN) to classify screening images into BI-RADS classes (BI-RADS 0, 1 and 2) before evaluation on a held-out set of exams.
Results: Area under the receiver operating characteristic curve (AUC) for BI-RADS 0 vs non-BI-RADS 0 class was 0.912 for the MV-CNN trained on the full dataset. The model obtained accuracy of 84.8%, recall of 95.9% and precision of 95.0%. This AUC value decreased when the same model was trained with 50% and 25% of images (AUC = 0.877, P=0.010 and 0.834, P=0.009 respectively). Also, the performance dropped when the same model was trained using images that were under-sampled by 1/2 and 1/4 (AUC = 0.870, P=0.011 and 0.813, P=0.009 respectively).
Conclusion: This deep learning model classified high-resolution synthetic mammography scans into normal vs needing further workup using tens of thousands of high-resolution images. Smaller training data sets and lower resolution images both caused significant decrease in performance.

乳腺癌被认为是一个主要的健康问题,是世界上妇女死亡的最大原因。因此,在这十年中,乳腺癌是第二种最常见的癌症,就出现频率而言,也是第五种最常见的癌症相关死亡原因。为了减少放射科医师的工作量,已经提出了各种CAD系统;计算机辅助诊断(CADi)和计算机辅助检测(CADe)。在本文中,我们感兴趣的CADe工具,以帮助放射科医生检测癌症。建议的CADe是基于一个三步的工作流程,即检测,分析和分类。研究了基于边缘和区域准则的水平集方法的感兴趣区域自动检测问题。这种方法从放射科医生那里得到了良好的视觉信息。在此基础上,采用基于纹理特征的图像特征提取和基于多层感知(MLP)和k-近邻(KNN)的图像矢量分类方法,对图像进行了ACR(American College of Radiology)分类。此外,我们使用数字数据库筛选乳腺X射线摄影(DDSM)的实验和这些结果的准确性在60%和70%之间变化是可以接受的,必须加以改进,以帮助放射科医生。

我们介绍了一种新的计算机辅助检测和诊断系统,肺癌筛查与低剂量CT扫描,产生有意义的概率评估。我们的系统完全基于3D卷积神经网络,并在公开的LUNA16和Kaggle Data Science Bowl挑战赛上实现了肺结节检测和恶性肿瘤分类任务的最新性能。虽然结节检测系统通常是自行设计和优化的,但我们发现,考虑检测和诊断组件之间的耦合是很重要的。利用这种耦合使我们能够开发一种端到端系统,该系统具有更高和更强大的性能,并消除了对结节检测假阳性减少阶段的需要。此外,我们在我们的深度学习系统中描述了模型的不确定性,这是肺部CT分析的第一个,并表明我们可以使用它来为结节检测和患者恶性肿瘤诊断提供校准良好的分类概率。这些由模型不确定性提供信息的校准概率可用于后续基于风险的诊断干预或疾病治疗决策,正如我们使用基于概率的患者转诊策略进一步改善我们的结果所证明的那样。
