Key Findings
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.

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.

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.

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.
