Automatic distinction between COVID-19 and common pneumonia using multi-scale convolutional neural network on chest CT scans

Abstract: Highlights A CT dataset contains 416 COVID-19 positive CT scans and 412 common pneumonia CT scans is publicly available. A multi-scale convolutional neural network can accurately differentiate COVID-19 and other common pneumonia on chest CT scans with limited number of training data. An AI system has comparable diagnostic sensitivity (89.1% vs 84.8%, p -value = 0.724), specificity (85.7% vs 83.3%, p … Show more

“…Apart from the CT scan segmentation and classification, deep learning models can help explain factors associated with COVID-19, e.g. in the form of attention maps [YMK + 20, YWR + 20] or using specialized tools like GSInquire [GWW20] that identify critical factors in CT scans. The advantage of using instance segmentation models like Mask R-CNN is the detection, scoring and segmentation of classified isolated areas that contribute to the condition (class of the image).…”

“…For this method, the images are synthetically increased using operations like image transformation (rotation, translation, and scaling), blurring, color jiggling, etc. There have been studies that use a patch-based framework with a relatively small number of trainable parameters for COVID-19 diagnosis, and use multi-scaling for spatial features [ 221 ] [ 222 ]. For the cross-validation (the 7 th attribute ) of the data, the K -fold strategy was used to evaluate the performance of the AI technique.…”
