CT Characteristic Appearances of Patients with Novel Coronavirus Pneumonia/ 新型冠状病毒肺炎胸部ct影像学特征分析

Objective: To summarize the imaging features of chest CT in patients with novel coronavirus pneumonia (NCP), and to explore its value in clinical diagnosis and treatment of NCP Methods: The complete imaging data of 30 patients with NCP diagnosed in our hospital were analyzed retrospectively, focusing on the distribution, shape, density, location and stage of abnormal shadow in the chest CT Results: Chest CT scan showed that 28 patients had different degrees of abnormal pulmonary shadow Distribution of lesions: unilateral lobe (middle lobe of right lung) lesions in 2 cases (7 14%), single lung multi-lobar lesions in 1 case (3 57%) bilateral pulmonary multi-lobular lesions in 20 cases (71 43%) bilateral lower lung lesions in 2 cases (7 14%) double middle and lower lung lesions in 3 cases (10 72%) Locations of lesions: 15 cases (53 47%) were far from hilum of lung and located in the peripheral area 13 cases (46 43%) involved both the periphery and the center areas Morphology of lesions: lesions were patchy and partialy fused in 12 cases (42 85%) spherical lesions in 11 cases (39 29%)，while the other 5 cases (17 86%) showed both Density of lesions: the lesion density showed ground glass changes in 11 cases (39 29%) consolidation in 11cases (39 29%) and both in the remaining 6 cases 21 42%) Stages of lesions: 11 cases (39 29%) was early 13cases (46 43%) were progressive 4cases (14 28%) were severe Conclusions: NCP patients have characteristic chest CT findings CT scan and imaging staging are helpful to the early diagnosis and dynamic evaluation of disease condition and can be used in clinical treatment practice
