Abstract
Background: Currently the diagnosis of COVID-19 is based on RT-PCR which is gold standard. The drawback of this is that it is time consuming and has a very high false negative rate at the early stage of infections. As a supplement, chest CT examination may be an important and effective tool for screening, diagnosing, triage, prognostication and evaluating the disease progression and monitoring the response to therapy in patients with COVID-19 infection. With this background we aimed to describe the changes in chest CT in COVID-19 patients in our setting. Settings and Design: It is a cross-sectional study carried out in 150 patients who had undergone non-contrast chest CT. Patients with abnormal CT were divided into two groups: clinically stable (in-ward admission) and clinically unstable (ICU admission). Results: Lung parenchymal abnormalities were present in 48.7% of patients and remaining 51.3% patients had a normal chest CT. Age of the clinically stable group (47.8 ± 9.6) was significantly lower than the unstable group (65.6 ± 5.2). Central-peripheral and antero-posterior lung involvement was significantly more common among unstable group. GGO was the dominant opacity found in all 73 (100%) cases. The crazy paving pattern was more significantly seen in unstable patients than in stable patients (73.3% and 22.4% respectively). Conclusions: Chest HRCT scan plays an important role in the early diagnosis and disease stratification of COVID-19.
