Abstract: Medical imaging techniques have a potentially important role to play in early diagnosis and managing the treatment of patients infected with SARS-CoV-2. Chest CT, as a routine imaging tool for pneumonia diagnosis, is relatively easy to perform and can produce fast diagnosis. Several chest CT features of COVID-19 pneumonia are reported in previous studies; however, limited imaging data of Indian patients is available. The objectives of this study are to study the spectrum of chest computed tomographic (CT) imaging findings in coronavirus. disease-19 (COVID-19) infected Indian patients , to estimate CT severity index and mortality rate and to study the correlation of CT severity index with age, gender and mortality. This study included 220 patients with diagnosis of COVID-19 infection confirmed by nucleic acid testing. The lung parenchymal abnormality was seen in all patients. Bilateral lung involvement was present in 217 (98.6%) patients. GGO was the dominant opacity found in all 220 (100%) cases. There was no statistically significant correlation of CT severity score and gender (p value = 0.316).This study showed significant correlation of CT severity score and increasing age (p value = 0.003).There was significant correlation between high CT severity score and mortality rate (p-value= 0.001).
