Abstract: Objective: association of HRCT chest involvement score in COVID-19 infections with clinical severity and outcome of patients. HRCT chest helps to identify hidden cases of COVID-19 pneumonia which helps to prevent further transmission. Methods: This was retrospective study carried out from October 24, 2020, until april 28, 2020 consists of 147 patients including suspicious and positive RT-PCR for COVID-19 pneumonia. Each scan were reported with involvement score and categorized as mild, moderate and severe as per score range. Results: In our study ground glass opacity was found in every patient. The association between CT score and final outcome has significant association as score rises. Conclusion: Hight the CT involvement score higher the mortality. This can be used to triage patients while limited resources are available.
