Interpretation of CT signs of 2019 novel coronavirus (COVID-19) pneumonia.

Objectives: To characterize and interpret the CT imaging signs of the 2019 novel coronavirus (COVID-19) pneumonia in China.

Materials And Methods: The CT images of 130 patients diagnosed as COVID-19 pneumonia from several hospitals in China were collected and their imaging features were analyzed and interpreted in detail.

Results: Among the 130 patients, we can see (1) distribution: 14 cases with unilateral lung disease and 116 cases with bilateral disease, the distribution was mainly lobular core (99 cases) and subpleural (102 cases); (2) number: 9 cases with single lesion, 113 cases with multiple lesions, and 8 cases with diffuse distribution; (3) density: 70 cases of pure ground glass opacity (GGO), and 60 cases of GGO with consolidation; (4) accompanying signs: vascular thickening (100 cases), "parallel pleura sign" (98 cases), "paving stone sign" (100 cases), "halo sign" (18 cases), "reversed halo sign" (6 cases), pleural effusion (2 cases), and pneumonocele (2 cases).

To investigate the imaging findings of 2019 novel coronavirus pneumonia (COVID-19). From January 20 to February 5, 2020, a total of 130 patients diagnosed with COVID-19 from seven hospitals in China were collected. The imaging data were reviewed and analyzed in detail.
