In this study, the diagnostic performance of the structured approach of chest radiograph was evaluated and compared with RT-PCR. The study revealed that positive chest radiography had a high likelihood of predicting a positive RT-PCR. The accuracy of baseline CXR in the diagnosis of COVID-19 is moderate to good, with high specificity and low sensitivity. The Chest radiographs (CXR) are an alternative to the CT scans taken for the COVID-19 diagnosis.
The graphs obtained have low sensitivity hence further validation is required.

Comparative study of diagnosis of COVID-19 by chest CT scans and RT-PCR assay showed that chest CT scans for the primary screening of COVID-19 showed a low positive predictive value than RT-PCR assay. For chest CT scans and RT-PCR, the Positive predictive value ranged from 1.5%-30.7% and 47.3%-96.4%, respectively.

This research focuses on the relation between the RT-PCR test and Chest CT scan. Chest CT had higher sensitivity for the diagnosis of COVID-19 as compared with RT-PCR assay. The Chest CT scans were taken serially and divided into highly likely, probable, and uncertain cases, based on clinical features and the presence of ground-glass opacities. RT-PCR can be affected by a number of external factors whereas Chest CT scans are non-invasive with high accuracy

A comparative study between the RT-PCR and the Chest CT scans revealed that chest CT had greater sensitivity than RT-PCR. Thus, chest CT scans can be recommended for primary screening of COVID-19 infections when the RT-PCR test is negative. A comparision between the RT-PCR and the Chest CT scans highlight the drawbacks of nucleic acid testing that include immature technology, detection variability, low patient viral load and improper sample handling therefore a Chest CT scan should be done for the screening of COVID-19 patients

In this study, chest CT imaging of five COVID-19 patients who had initial negative RT-PCR results revealed typical imaging findings (ground-glass opacity, mixed GGO, and mixed consolidation). Thus, chest CT scans can be recommended for primary screening of COVID-19 infections when the RT-PCR test is negative. The patients were divided into four categories mild, common, severe and fatal types

In this study, the CT features of COVID-19 were reported and compared with the CT features of other viruses to find the possible CT patterns. The study revealed that chest CT had a low rate of misdiagnosis of COVID-19 (3.9%). The two major signs of COVID-19 are ground glass opacities and consolidation. The minor signs included vascular enlargement, interlobular septal thickening, air bronchogram sign and reverse halo signs.
