Study of the Correlation Between CT Pattern and Clinical Presentation in Confirmed Cases of Covid-19 Pneumonia

Abstract

n Febreury, 2020 with start of COVID pandemic, chest CT outperformed lab testing in the diagnosis of 2019 novel corona virus disease (COVID-19). The researchers concluded that CT should be used as the primary screening tool for COVID-19 early identification and treatment are therefore essential in COVID-19 management. This retrospective study observed the correlation between CT pattern and clinical manifestation of COVID 19 patients. We aim to help in understanding the radiographic development of the new pandemic by analyzing the correlation between the clinical course of COVID-19 and its radiographic progression on CT. We observationally collected the records of patients with RT-PCR-confirmed COVID-19 in Ain-Shams University Hospitals from 12th of June, 2021 till 12th of August, 2021. A total of 100 patients with consecutively laboratory-confirmed COVID-19 (35 women, 65 men; mean age, 59.22 ± 13.70 [SD] years; median, 58 years; range, 28–87 years). All patients performed HRCT chest in the time of their presentations and the different CT findings were mentioned and severity of the disease were calculated according to summation of the areas affected in different lung lobes in both lobes using the Total Severity Score and accordingly cases classified into mild, moderate and severe. All clinical data including non-respiratory
