DCNNV-19: A Deep Convolutional Neural Network for COVID-19 Detection in Chest Computed Tomographies
This provides a rapid diagnostic tool for suspected COVID-19 patients, especially where RT-PCR delays could cause health damage, but it is incremental as it applies an existing method to a new medical dataset.
The paper tackles COVID-19 detection in chest CT scans by proposing a deep convolutional neural network, achieving an F1-Score of 98%, accuracy of 98.4%, and faster results than RT-PCR.
This technical report proposes the use of a deep convolutional neural network as a preliminary diagnostic method in the analysis of chest computed tomography images from patients with symptoms of Severe Acute Respiratory Syndrome (SARS) and suspected COVID-19 disease, especially on occasions when the delay of the RT-PCR result and the absence of urgent care could result in serious temporary, long-term, or permanent health damage. The model was trained on 83,391 images, validated on 15,297, and tested on 22,185 figures, achieving an F1-Score of 98%, 97.59% in Cohen's Kappa, 98.4% in Accuracy, and 5.09% in Loss. Attesting a highly accurate automated classification and providing results in less time than the current gold-standard exam, Real-Time reverse-transcriptase Polymerase Chain Reaction (RT-PCR).
