论文摘要
快速准确的诊断对于减轻Covid-19感染的影响至关重要,尤其是对于严重病例。已经为开发深度学习方法而付出了巨大的努力,以从胸部X射线照相图像分类和检测COVID-19的感染。但是,最近在此类方法的临床生存能力和有效性周围提出了一些问题。在这项工作中,我们研究了多任务学习(分类和分割)对CNN区分肺中Covid-19感染各种外观的能力的影响。我们还采用了自我监管的预训练方法,即Moco和Inpainting-CXR,以消除对COVID-19分类的昂贵地面真相注释的依赖。最后,我们对模型进行了批判性评估,以评估其部署准备,并提供有关胸部X射线的细粒度Covid-19多级分类困难的见解。
Quick and accurate diagnosis is of paramount importance to mitigate the effects of COVID-19 infection, particularly for severe cases. Enormous effort has been put towards developing deep learning methods to classify and detect COVID-19 infections from chest radiography images. However, recently some questions have been raised surrounding the clinical viability and effectiveness of such methods. In this work, we investigate the impact of multi-task learning (classification and segmentation) on the ability of CNNs to differentiate between various appearances of COVID-19 infections in the lung. We also employ self-supervised pre-training approaches, namely MoCo and inpainting-CXR, to eliminate the dependence on expensive ground truth annotations for COVID-19 classification. Finally, we conduct a critical evaluation of the models to assess their deploy-readiness and provide insights into the difficulties of fine-grained COVID-19 multi-class classification from chest X-rays.
