HRCT Chest Manifestations of COVID-19 Pneumonia in a Time Series

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in December 2019 in Wuhan, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic. Due to the widespread of the virus in the Kingdom of Saudi Arabia, the study tried to help find features of additional diagnostic methods (HRCT) for the disease to facilitate its detection and treatment in a timely manner before the complications increase. The purpose of this study was to assess the clinical features and HRCT chest manifestations of COVID19 pneumonia by gathered a sample of (20) serial HRCT chest from the patients, three days after the symptoms began, then repeated after 48 hours, by this stage, the patient has had a positive nasopharyngeal swab for COVID-19 virus. The final HRCT was taken in the 10th day after symptoms. In 100 % of patients, 55 % were diagnosed with more diffused opacities in the all zones in 10th day of symptoms, a significant relationship was found between affected lung zones and the three-time series at p = 0.05. The study revealed a gradual spread that occurs over time for both GGO and consolidations, where the highest spread of both features was recorded on the tenth day in (90 % and 85 %) of patients for GGO and consolidation respectively, and there is a significant relationship between degree of GGO clarity, the amount of consolidation spread on HRCT and the three-time series at p = 0.01 for both features. Other findings like pleural effusion and crazy paving appearance …etc. were found in few patients, However, the study noted that those findings were more appear by time and significant relationship also noted between occurring of those other features in the three-time series after symptoms onset, and patients age at p=0.05. HRCT chest was more serviceable tool to follow the signs diffusion caused by COVID-19 virus in the lungs tissues over three dif
