Methods: A cross - sectional study was carried out on patients with positive RT-PCR test results for SARS-CoV-2 were treated at Trung Vuong hospital from June 2021 to March 2022. All patients wereexamined with chest CT scan. Chest CT imagings were taken by CT scanner Hitachi 128 Slice. The variables were the ways of distribution, the types of lesions and imagings of complications of COVID-19 disease. Results: Frequent abnormalities (lesions): ground - glass opacities (98,1%), consolidation (72,1%), Crazy - paving pattern (58,7%). Lymadenopathy appears 52,9%, in that, mediastinal lymph nodes 39,4%, axillary lymph nodes 13,5%. Subplueral fibrous band 12,5%. Plueral effusion 8,7%. Bronchiectasis 3,8%. Interlobular septal thickening 2,9%. Infrequent abnormalities: localized consolidation 1,9%, consolidated nodule 1,9%, collapsed lung 1,9%, vascular thickening 1,9%, pleural thickening 1,9%, emphysema 1%, multi ground - glass opacities nodules 1,9%. Chest CT of COVID-19 Complications: ARDS 5,8 %, pericardial effusion 6,7%, superimposed pneumonia 8,7%, pneumomediastinum 3,8%, pneumo pleural 1% Conclusion: Chest CT scan should be performed in the diagnosis of COVID-19 pneumonia, especially in the early stage. In the late stage, chest CT helps to predict and monitor treatment.
