- Abstract summary: We introduce COVID-Net CXR-S, a convolutional neural network for predicting the airspace severity of a SARS-CoV-2 positive patient based on a CXR image of the patient's chest.
We leveraged transfer learning to transfer representational knowledge gained from over 16,000 CXR images from a multinational cohort of over 15,000 patient cases into a custom network architecture for severity assessment.
The proposed COVID-Net CXR-S has potential to be a powerful tool for computer-aided severity assessment of CXR images of COVID-19 positive patients.

- Abstract: The world is still struggling in controlling and containing the spread of the
COVID-19 pandemic caused by the SARS-CoV-2 virus. The medical conditions
associated with SARS-CoV-2 infections have resulted in a surge in the number of
patients at clinics and hospitals, leading to a significantly increased strain
on healthcare resources. As such, an important part of managing and handling
patients with SARS-CoV-2 infections within the clinical workflow is severity
assessment, which is often conducted with the use of chest x-ray (CXR) images.
In this work, we introduce COVID-Net CXR-S, a convolutional neural network for
predicting the airspace severity of a SARS-CoV-2 positive patient based on a
CXR image of the patient's chest. More specifically, we leveraged transfer
learning to transfer representational knowledge gained from over 16,000 CXR
images from a multinational cohort of over 15,000 patient cases into a custom
network architecture for severity assessment. Experimental results with a
multi-national patient cohort curated by the Radiological Society of North
America (RSNA) RICORD initiative showed that the proposed COVID-Net CXR-S has
potential to be a powerful tool for computer-aided severity assessment of CXR
images of COVID-19 positive patients. Furthermore, radiologist validation on
select cases by two board-certified radiologists with over 10 and 19 years of
experience, respectively, showed consistency between radiologist interpretation
and critical factors leveraged by COVID-Net CXR-S for severity assessment.
While not a production-ready solution, the ultimate goal for the open source
release of COVID-Net CXR-S is to act as a catalyst for clinical scientists,
machine learning researchers, as well as citizen scientists to develop
innovative new clinical decision support solutions for helping clinicians
around the world manage the continuing pandemic.
