Aim CT has an important place in diagnosing SARS-CoV-2 due to the RT-PCR test's high false-negative rate and the faster evaluation of CT, although the RT-PCR test is the gold standard. This study aims to understand chest CT features and distributions in patients with SARS-CoV-2 proven by RT-PCR. Materials and Methods This study is retrospective and includes one hundred adult patients with confirmed SARS-CoV-2 infection who admitted to the hospital. The Chest CT findings of these patients were retrospectively recorded. Radiological Society of North America reporting guidelines for SARS-CoV-2 pneumonia was referenced to classify chest CT findings. Results In SARS-CoV-2 patients confirmed by RT-PCR, the mean age of 79 pneumonia patients (54.0216.99) was higher than age of patients without pneumonia (42.4717.78). Prevalences of ground-glass opacity, consolidation, posterior dominance, bilaterality, peripheral distribution, multifocality, vascular enlargement, pleural effusion, lymphadenopathy, tree-in-bud pattern, halo sign and reverse halo sign were 74.68%, 3.79%, 17.72%, 43.03%, 70.88%, 84.81%, 84.81%, 12.65%, 2.53%, 1.26%, 2.53%, 8.86%, and 3.79%, respectively. Conclusion This study's findings indicate that common chest CT findings in SARS-CoV-2 pneumonia are ground glass opacities with multifocal, multilobar, peripheral and bilateral involvement. No significant result was shown in favor of posterior or lower lobe dominance. According to the present study, SARS-CoV-2 patients are more likely to get pneumonia as they get older. |
