Abstract:

Objective: To assess the screening utility of HRCT chest in COVID- 19 pneumonia by comparing sensitivities of HRCT Chest and rt-PCR in clinically confirmed patients. Study Design: Cross sectional validation study Place and Duration: Department of Radiology and Medicine of Combine d Military Hospital Okara from 1st September 2020 to 28th February2021. Methodology: All clinically confirmed COVID patients were included in the study by using non-probability consecutive sampling. Findings of HRCT chest and results of rt-PCR were assessed by comparing the diagnostic sensitivities of HRCT Chest and rt-PCR for the patients. Results: a total of 689 patients (80.6% males and 19.4% females) with mean age of 51.45±14.58 years were assessed. They showed sensitivity of HRCT of 91.8% as compared to the PCR sensitivity of 84.7% in highly suspected cases of COVID-19 pneumonia. Conclusion: HRCT chest has higher sensitivity in detecting COVID-19 pneumonia than PCR and hence proves to be a better, quick and reliable screening tool than rt-PCR for COVID-19 pneumonia.
