Background
Computed tomography plays an important role in diagnosing and following up cases of COVID-19 infection and its complications, as current guidelines indicate the use of high-resolution computed tomography in patients with COVID-19 thanks to its high accuracy in detecting lung changes in viral pneumonia, and to rule out other causes. For pneumonia.
Methods and Materials:
A retrospective, cross-sectional study was conducted in Damascus Hospital (Al-Mujtahid), by referring to the records and files of Corona patients admitted to the hospital during the peak of the first Corona infection in the Syrian Arab Republic during a period of 5 months from the first month of 2020 AD until the fifth month in The second peak in 2021 AD, from month 5 to month 8. The study included 225 patients out of 286 patients who met the exclusion and inclusion criteria.
Results
The percentage of infiltrates on plain chest CT, segmental infiltrates, and hemipectoral shadow were 8.7%, 26.2%, and 2.09%, respectively. Radiological signs on CT in our study: ground glass densities in 95%, pulmonary condensation syndrome in 86%. Tile sign 75%, pulmonary caverns 5%, pulmonary nodules forming in the center of the lobule 7%, tree bud view 9%, thickening of interlobular occlusions 16%, perilobular densities 25%, reticular infiltrates 16%, phlegmon nodular hyperplasia 20%, pleural effusion 3%.
Conclusion
The COVID-19 pandemic has dramatically changed human routines and the healthcare sector, and it is essential for radiologists to be aware of the basic clinical and radiological aspects of COVID-19.
