    Background: Although CT characteristics of Coronavirus Disease MESHD 2019 (COVID-19) pneumonia HP pneumonia MESHD between patients with mild and severe forms of the disease have already been reported in the literature, there was little attention to the correlation of imaging features and laboratory testing. We aimed to compare the laboratory and chest CT imaging features in patients with COVID-19 pneumonia HP pneumonia MESHD between non-severe cases and severe cases, and to analyze the correlation of CT score and laboratory testing.Methods: This study consecutively included 54 patients with COVID-19 pneumonia HP pneumonia MESHD (26 males TRANS and 28 females TRANS, 26 to 92 years of age TRANS, 43 cases with non-severe and 11 cases with severe group). Clinical, laboratory and image data were collected between two subgroups. A CT score system was used to evaluate the extent of disease. Correlation between the CT score and laboratory data were estimated. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance SERO of CT score and laboratory tests.Results: Compared with non-severe patients, severe patients had showed increased white blood SERO cell count, neutrophil count, neutrophil percentage, the neutrophil-to-lymphocyte ratio (NLR) and decreased lymphocyte percentage (all p < 0.05). Architectural distortion, pleural effusion HP pleural effusion MESHD, air bronchogram and consolidation-dominant pattern were more common in the severe group (all p < 0.05). CT score of the severe group was higher than the non-severe group (p < 0.001). For distribution characters of the lesions, diffuse pattern in the transverse distribution was more often seen in the severe group (p < 0.001). CT score was positively correlated with the white blood SERO cell counts, neutrophil counts, the percent of neutrophil, NLR, alanine aminotransferase, lactate dehydrogenase and C-reactive protein, and was inversely related to the lymphocyte, the percent of lymphocyte. ROC analysis showed that when the optimal threshold of CT score was 13, the area under the curve was the largest, which was 0.855, and the sensitivity SERO and specificity were 100% and 60% respectively for the diagnosis of the severe patients.Conclusion: CT score showed significant correlations with laboratory inflammatory markers, suggesting that chest CT and laboratory examination maybe provide a better reference for clinicians to judge the severity of diseases.

    Background – COVID-19 associated Multisystem Inflammatory Syndrome in Children TRANS (MIS-C) is an emerging disease that presents with inflammation MESHD of multiple organs. The extracardiac radiographic manifestations of this syndrome are not well understood.Objective – We reviewed the radiologic findings of MIS-C in a cohort of children TRANS with a confirmed diagnosis of the syndrome.Materials and methods – In a retrospective study from 4/1/2020 to 5/22/2020, we reviewed imaging studies of 38 children TRANS with MIS-C, 21 females TRANS (55%) and 17 males TRANS (45%), with an average age TRANS of 9.2 years (range 1.3 – 20 years). Thirty six had chest radiographs, 6 had abdominal radiographs, 12 had abdominal sonograms or MRI, 2 had neck sonograms, and 3 had brain MRI.Results – 28 patients had pulmonary disease MESHD, with 24 (86%) having bilateral opacities, mostly diffuse (n=16, 57%). The most common abnormalities were peribronchial thickening (n=19, 68%), ground glass opacities (n=15, 54%) and consolidation (n=5, 18%). Pleural effusions HP Pleural effusions MESHD were only present in children TRANS 10 years of age TRANS and under, and ground glass opacities were seen more often in older patients (59% vs. 26%, P<0.05). On abdominal imaging, small volume ascites HP ascites MESHD was the most common finding (n=6, 50%). Other findings included right lower quadrant bowel wall thickening (n=3, 25%), gallbladder wall thickening (n=3, 25%), and cervical (n=2) or abdominal (n=2) lymphadenophathy. Of 3 patients with brain MRI, one had bilateral parietooccipital abnormalities MESHD and another papilledema HP papilledema MESHD.Conclusion – COVID-19 associated MIS-C causes a constellation of findings in the chest and abdomen, most often showing bilateral diffuse pulmonary abnormalities MESHD and small volume ascites MESHD ascites HP

    BackgroundCOVID-19, a worldwideinfectious disease MESHD, has killed more than 420000 people, whichis extremely harmful.MethodsIn this single-center retrospective study, we included the novel coronavirus pneumonia MESHD pneumonia HP confirmed in our hospital. This study collected the basic information andclinical examination features.ResultsThe enrolled 704 patients were affirmed infected with 2019-nCoV by the test of throat swabs. There are 334 men and 369 women, and gender TRANS, age TRANS, combined with basic diseasesare distinct in diverse disease classification (p<0.05). From the symptom analysis, the proportion of fever HP fever MESHD over 38 degrees, dyspnea HP dyspnea MESHD, fatigue HP fatigue MESHD, poor appetite HP and other symptoms is diverse in different types of diseases (p<0.05). As the severity of the disease increases, the median lymphocyte count decreases, C-reactive protein increase, erythrocyte sedimentation rateincrease, albumin decrease, pleural effusion HP pleural effusion MESHD increase, D-Dimer and NT-proBNP increase significantly (p<0.05).As the disease severity increases, the average value of MuLBSTA score obviously ascend (p<0.05), MuLBSTA scoring system predicts novel coronavirus pneumonia MESHD pneumonia HP patients' prognosis is still insufficient, and may require additional indicators including anorexia HP anorexia MESHD, fatigue HP fatigue MESHD, C reactive protein, etc (p<0.05).ConclusionThe MuLBSTA evaluation system has certain value for the evaluation of the disease, but it needs to be improved.

    Background Coronavirus disease MESHD 2019 (COVID-19) pneumonia HP pneumonia MESHD caused similar symptoms to other community-acquired pneumonia HP pneumonia MESHD (CAP). It is important to early quarantine suspected patients with COVID-19 pneumonia HP pneumonia MESHD from patients with other CAP to reduce cross infection MESHD. The purpose of the study is to review and compare initial thin-section computed tomography (CT) features in patients with coronavirus disease MESHD 2019 (COVID-19) pneumonia HP pneumonia MESHD and other community-acquired pneumonia HP pneumonia MESHD (CAP). Methods 24 cases of COVID-19 pneumonia HP pneumonia MESHD (14 males TRANS and 10 females TRANS; age TRANS range, 14-87 years; mean age TRANS, 48.0 years) and 28 cases of CAP caused by other pathogens (13 males TRANS and 15 females TRANS; age TRANS range, 24-85 years; mean age TRANS, 49.5 years) were included. Thin-section CT features of the lungs for all patients were retrospectively reviewed by two independent radiologists. Results There were no significant differences for the shape of main lesions, pure ground glass attenuation (GGA), mixed GGA with consolidation, air bronchogram, linear opacities, halo sign/reversed halo sign, cavitation and lymphadenopathy HP lymphadenopathy MESHD between the group of COVID-19 pneumonia HP pneumonia MESHD and the group of other CAP. However, the frequency of crazy-paving appearance, vessel dilatation HP, bilaterally involvement and peripherally distribution were significantly higher in patients with COVID-19 compared with other CAP ( p =0.031, p =0.000, p =0.029 and p =0.009, respectively). Conversely, the frequencies of pure consolidation, tree-in-bud sign and pleural effusion HP pleural effusion MESHD were significantly higher in patients with CAP than in patients with COVID-19 pneumonia HP pneumonia MESHD ( p =0.002, p =0.000 and p =0.048, respectively). Conclusion There are considerable overlaps in thin-section CT features between COVID-19 pneumonia HP pneumonia MESHD and other CAP. However, the presence of crazy paving pattern, vessel dilation, bilateral involvement and peripheral distribution contributes to the diagnosis of COVID-19 pneumonia HP pneumonia MESHD. While the presence of pure consolidation tree-in-bud sign, pleural effusion HP pleural effusion MESHD can be assisting in exclusive the diagnosis of COVID-19 pneumonia HP pneumonia MESHD.

    Purpose: Due to the emergence of the new Coronavirus-2019 and the lack of sufficient information about infected patients, this study was conducted to investigate the Chest High Resolution Computed Tomography (HRCT) findings of patients infected with the new Coronavirus 2019.Methods: This cross-sectional study was performed on COVID-19 patients referred to Medical Imaging Centers of Sari, Mazandaran, Iran, on March 2020 for Computed Tomography Scan (CT-Scan). Symptomatic patients were referred to the Medical Imaging Center for diagnosis confirmation through CT-scan. In addition to age TRANS and sex, HRCT findings were collected from the picture archiving and communication system (PACS) for further evaluations.Results: Out of 552 patients with mean age TRANS of 14.8 ± 51.2 years, the male TRANS/ female TRANS ratio was 1.38 to 1. The most common expressive findings in patients were ground-glass opacity (GGO) (87.3%), peripheral distribution (82.4%) and posterior distribution (81.5%). The most conflicting findings in patients were pleural effusion HP pleural effusion MESHD (7.6%), peribronchovascular distribution (7.6%), and lymphadenopathy HP lymphadenopathy MESHD (5.1%). The peripheral distribution (p = 0.034), round opacities (p = 0.02), single lobe (p = 0.003) and pleural effusion HP pleural effusion MESHD (p = 0.037) were significantly in people under and over 50 years of age TRANS.Conclusion: In summary, the present study indicated that in addition to GGO, peripheral distribution findings could be a vital diagnostic choice in COVID-19 patients.

    Objectives: No data were available about in-flight transmission TRANS of SARS-CoV-2. Here, we report an in-flight transmission TRANS cluster of COVID-19 and describe the clinical characteristics of these patients. Methods: After a flight, laboratory-confirmed COVID-19 was reported in 12 patients. Ten patients were admitted to the designated hospital. Data were collected from 25th January to 28th February 2020. Clinical information was retrospectively collected. Results: All patients are passengers without flight attendants. The median age TRANS was 33 years, and 70% were females TRANS. None was admitted to intensive care unit, and no patients succumbed through 28th February. The median incubation period TRANS was 3.0 days and from illness onset to hospital admission was 2 days. The most common symptom was fever HP fever MESHD. Two patients were asymptomatic TRANS and negative for chest CT scan throughout the disease course. On admission, initial RT-PCR were positive in 9 patients, however initial chest CT were positive in only half patients. The median lung total severity score of chest CT was 6. Notably, Crazy-Paving pattern, pleural effusion HP pleural effusion MESHD, and ground-glass nodules were also seen. Conclusion: It is potential for COVID-19 transmission TRANS by airplane, but the symptoms are mild. Passengers and attendants must be protected during the flight.

    Background: Imagery techniques have been used as essential parts of diagnostic workup for patients suspected for 2019-nCoV infection MESHD, Multiple studies have reported the features of chest computed tomography (CT) scans among a number of 2019-nCoV patients. Method: Study Identification was carried out in databases (PubMed, Embase and Cochrane Library) to identify published studies examining the diagnosis, the 2019 novel coronavirus (2019-nCoV). Heterogeneity among reported prevalence SERO was assessed by computing p-values of Cochrane Q-test and I2-statics. The pooled prevalence SERO of treatment failure was carried out with a fixed effects meta-analysis model, generating the pooled 95% confidence interval. A random-effect model was used to pool the results since this model could incorporate the heterogeneity of the studies and therefore proved a more generalized result. Results: According to the combined results of meta-analysis, the total 55% of corona patients were males TRANS. The mean age TRANS of the patients was 41.31 (34.14, 48.47). Two prevalent clinical symptoms between patients were fever HP fever MESHD, cough HP cough MESHD with prevalence SERO of 85%, and 62%, respectively. Either Ground Glass Opacity GGO or consolidation was seen in 86% but 14% had NO GGO or consolidation. The other rare CT symptoms were pericardial effusion HP, and pleural effusion HP pleural effusion MESHD with 4, 5, 7% prevalence SERO, respectively. The most prevalent event was Either GGO or consolidation in 85% of patients. Conclusion: The most CT-scan abnormality is Either Ground Glass Opacity GGO or consolidation however in few patients none of them might be observed, so trusting in just CT findings will lead to miss some patients.
