Objective: To discuss the early imaging features of novel coronary pneumonia (NCP) and its differential diagnosis with common pneumonia for the clinical Provide relatively correct imaging diagnosis. Methods: A review of 10 cases of novel coronavirus pneumonia diagnosed in our hospital and surrounding counties was collected, and our hospital's 2019-2020 Common pneumonia such as influenza A and B virus pneumonia, lobar pneumonia and adenovirus confirmed by laboratory tests and abnormal chest radiographs Ten patients each with pneumonia, a total of 40 patients, were collected and their imaging features were analyzed. Results: In 10 patients with neo-coronary pneumonia, there were 30 lesions on chest CT, with typical characteristic lesions containing bronchograms within their Angiographic thickening; located in the subpleura, with grinding glass-like or combined solid changes, referred to as "extratubular halo", with multifocal and multifocal distribution. Morphology or unilobular large lamellar foci without lymph node enlargement and pleural effusion; 10 cases of influenza A and B virus pneumonia in chest CT performance In nine patients, the lesions were distributed in the subpleural or along the perimeter of the bronchial vessels in the form of an analogous circular ground-glass shadow, some of which was a small piece of solid shadow, 1 The case involved a single lobe of the lung and showed a large mixed ground glass image, and the CT in 10 cases of lobar pneumonia showed that they all had a single large solid lobe The variegated shadow or patchy cloud with blurred margins was triangularly altered with the tip pointing to the lung portal, and there were five cases of air-containing bronchograms. Adenoviral pneumonia is more common in infants and young children, and CT showed single or multiple grinded glass images in both lungs with patchy solid variegated shadows and lobar distribution. Conclusion: NCP and common pneumonia have certain imaging features that, in combination with laboratory tests and epidemiologic history, allow a preliminary diagnosis to be made. It has certain directions and help for clinical diagnosis.
