    Background: The aim of the study is to investigate the pulmonary CT signs in patients with confirmed COVID-19 infection MESHD. This study included 100 patients, 54 male TRANS and 46 female TRANS their ages TRANS ranged from 6 to 85 years. All Patients tested positive for COVID-19 infection by RT-PCR test included in this study. All the patients performed pulmonary CT scan and the CT findings were evaluated.Results: 90 patients (90%) had abnormal pulmonary CT. Two lungs affected in 79 patients (79%). Lesions involved 1 lobe (11%), 2-3 lobes (35%) and 4-5 lobes (44%). The most involved pulmonary lobes MESHD were right lower lobe (77 patients, 77%), followed by left lower lobe (71 patients, 71%), the most involved pulmonary segments were posterior segments (69 patients, 69%),peripheral sub- pleural lesions MESHD were the commonest lesions location (64 patients, 64%). The most common lesions pattern were ground glass pattern (44 patients, 44%), followed by mixed ground glass and consolidation patterns (33 patients, 33%). The commonest lesion shape was patchy opacities (40 patients, 40%). Reversed halo sign (28 patients, 28%), air bronchogram sign (39 patients, 39%), crazy paving pattern (77 patients, 77%), vascular thickening (66 patients, 66%), and pleural thickening HP pleural thickening MESHD (7 patients, 7%) CONCLUSION: The main pulmonary CT signs in patients with COVID-19 infection MESHD are bilateral, peripheral, multi-lobar patchy and nodular Ground glass opacification with or without consolidation. Other signs may also present include crazy paving pattern, reversed halo sign vascular thickening, and air bronchogram sign with no extra-pulmonary signs except for few pleural thickening HP pleural thickening MESHD.

    Background: An ongoing outbreak of mystery pneumonia MESHD pneumonia HP in Wuhan was caused by coronavirus disease MESHD 2019 (COVID-19). The infectious disease MESHD disease has spread TRANS globally and become a major threat to public health. Purpose: We aim to investigate the ultra-high-resolution CT (UHR-CT) findings of imported COVID-19 related pneumonia HP pneumonia MESHD from the initial diagnosis to early-phase follow-up. Methods: This retrospective study included confirmed cases TRANS with early-stage COVID-19 related pneumonia HP pneumonia MESHD imported from the epicenter. Initial and early-phase follow-up UHR-CT scans (within 5 days) were reviewed for characterizing the radiological findings. The normalized total volumes of ground-glass opacities (GGOs) and consolidations were calculated and compared during the radiological follow-up by artificial-intelligence-based methods. Results: Eleven patients (3 males TRANS and 8 females TRANS, aged TRANS 32-74 years) with confirmed COVID-19 were evaluated. Subpleural GGOs with inter/intralobular septal thickening were typical imaging findings. Other diagnostic CT features included distinct margins (8/11, 73%), pleural retraction MESHD or thickening (7/11, 64%), intralesional vasodilatation (6/11, 55%). Normalized volumes of pulmonary GGOs (p=0.003) and consolidations (p=0.003) significantly increased during the CT follow-up. Conclusions: The abnormalities of GGOs with peripleural distribution, consolidated areas, septal thickening, pleural HP pleural involvement MESHD and intralesional vasodilatation on UHR-CT indicate the diagnosis of COVID-19. COVID-19 cases could manifest significantly progressed GGOs and consolidations with increased volume during the early-phase CT follow-up.

    Objective: To assess the characteristics of computed tomography (CT) features and changes in CT monitoring in patients with novel coronavirus pneumonia HP (NCP) . Methods: In this retrospective, two-center study, we reviewed the medical records of 57 patients with NCP in CT from January 21 to February 12, 2020. Cases were confirmed TRANS by the results of nucleic acid test positive, and were analyzed for demographic, clinical, and CT features. Results: Of the 57 patients, 31cases were male TRANS, and 45.6% were female TRANS. The average age TRANS was 46.5 years. Patients had fever HP (84.2%), cough HP (49.1%), weak (31.6%), muscle ache (17.5%), shortness of breath (12.3%). The distribution of abnormality was a subpleural lesions in 51 cases, with 96.5% ground-glass opacity (GGO) and 68.4% consolidation. Another observation reveals 45.6% fibrosis, 33.3% lymph node enlargement, 21.1% pleural thickening HP, 17.5% small nodule, 7.0% white lung, 5.3% emphysema HP, and 3.5% bronchiectasis HP. Importantly, the group of men had more septal thickening and air trapping than the female TRANS group (p < 0.05); Compared with the younger, the elderly TRANS had higher of subpleural lesion, interlobular septal thickening and pleural HP thickening (p < 0.05). In the first monitoring, there were 37.3% improvement, 60.8% progress. In the second monitoring, there were 55% improvement, 35% progress. The improvement rate during the third follow-up visit was 100%. Conclusions: CT features and CT dynamic observation play a vital role in the diagnosis and treatment with NCP. It is conducive to early diagnosis, deepen the knowledge of NCP and accumulate experience.
