Drawing insights from COVID-19-infected patients using CT scan images and machine learning techniques: a study on 200 patients

Abstract: As the whole world is witnessing what novel coronavirus (COVID-19) can do to the mankind, it presents several unique features also. In the absence of specific vaccine for COVID-19, it is essential to detect the disease at an early stage and isolate an infected patient. Till today there is a global shortage of testing labs and testing kits for COVID-19. This paper discusses about the role of machine learning techniques for getting important insights like whether lung computed tomography (CT) scan should be the … Show more

“…Pedro et al 15 have utilized the EfficientNet 16 model along with transfer learning citetranferlearning and have achieved accuracies 87.60% and 98.99% for COVID-CT dataset 11 and SARS-CoV-2 CT-scan dataset 8 respectively. Sharma et al 17 have applied ResNet 14 on the database consisting of datasets: (i) GitHub COVID-CT dataset 11 , (ii) COVID dataset provided by Italian Society of Medical and Interventional Radiology 18 , (iii) dataset provided by hospitals of Moscow, Russia 19 , (iv) dataset provided by SAL Hospital, Ahmedabad, India 20 and have obtained almost 91% accuracy.…”

“…The diagnosis of COVID-19 should be based on RT-PCR or antibody tests. Due to the changing standard for diagnosis, the shortage of testing kits in some regions, and the unsatisfactory accuracy of laboratory tests, 13,14 a CT finding or a consensus based on symptoms by ≥2 skillful physicians was also acceptable. No restriction was cast on cancer types, but cancer needed to be concurrent with COVID-19, and a cancer history was obviously unacceptable.…”

“…They used 1262 CT images of COVID-19-positive cases and 1230 CT images of normal patients to secure an accuracy of 96.25% while F1 score of 96.29% with addition of data augmentation technique. Similarly, Sharma [ 40 ] designed a customized CNN-based ResNet50 architect as an automated tool for coronavirus disease diagnosis using 2200 computed tomography images of lungs (800 belongs to COVID-19 positive while 1400 of other pneumonia and normal patients) that attained 91.0% accuracy with sensitivity of 92.1%.…”
