Title:<\/strong> Comparison of CNN architectures and training strategies for quantitative analysis of idiopathic interstitial pneumonia. Projection to COVID follow-up strategies.<\/p>\n Abstract.<\/strong> Fibrosing idiopathic interstitial pneumonia (IIP) is a subclass of interstitial lung diseases manifesting as progressive worsening of lung function. Such degradation is a continuous and irreversible process which requires quantitative follow-up of patients to assess the pathology occurrence and extent in the lung. The development of automated CAD tools for such purpose is oriented today towards machine learning approaches and in particular convolutional neural networks. The difficulty remains in the choice of the network architecture that best fit to the problem, in straight relationship with available databases for training. In this work we investigate two CNN architectures and different training strategies in the context of a limited database, with high class imbalance and subjective and partial annotations. We show that increased performances are achieved using an end-to-end architecture versus patch-based, but also that naive implementation in the former case should be avoided. The proposed solution is able to leverage global information in the scan and shows a high improvement in the F1 scores of the predicted classes and visual results of predictions in better accordance with the radiologist expectations. The end of presentation will highlight potential applications of the developed solution to COVID-19 patients follow-up, together with additional image biomarkers related to vascular remodeling and lung compliance.<\/p>\n","protected":false},"excerpt":{"rendered":" L’\u00e9quipe ARMEDIA vous convie \u00e0 un s\u00e9minaire dans la th\u00e9matique \u00ab\u00a0IDIA et sant\u00e9\u00a0\u00bb le jeudi 25 juin \u00e0 14h00.
