新型冠状病毒肺炎胸部CT影像学特征分析

目的:总结新型冠状病毒肺炎(NCP)患者胸部CT影像学特征表现,探讨其对NCP临床诊治的价值。方法:回顾性分析本院目前收治已确诊NCP的30例患者完整影像学资料,重点观察有无胸部CT异常,并对胸部CT异常阴影的病变分布、形态、密度、位置、分期进行分析。结果:胸部CT扫描发现28例患者均有不同程度的肺部异常阴影。病变分布:单侧单叶(右肺中叶)病变2例(7.14%),单肺多叶病变1例(3.57%),双肺多叶病变20例(71.43%),双下肺病变2例(7.14%),双中下肺3例(10.72%);病变位置:病灶远离肺门,位于周边部位15例(53.47%),同时累及周边和中心13例(46.43%);病变形态:病灶表现为斑片状、部分融合呈大片状12例(42.85%),球形11例(39.29%),两者都有5例(17.86%);病灶密度:磨玻璃样改变11例(39.29%),实变11例(39.29%),两者均有6例(21.42%);病变分期:早期11例(39.29%),进展期13例(46.43%),重症4例(14.28%)。结论:新型冠状病毒肺炎患者具有特征性的胸部CT影像表现;CT扫描及影像分期有助于新冠肺炎的早期诊断及病情动态评估,可用于临床治疗实践。

CT characteristic appearances of patients with novel coronavirus pneumonia

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 partially 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 11 cases (39.29%), and both in the remaining 6 cases (21.42%). Stages of lesions:11 cases (39.29%) was early, 13 cases (46.43%) were progressive, 4 cases (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.
