摘　　要：目的初步探讨新型冠状病毒肺炎(COVID-19)的影像学表现。方法收集10例确诊为COVID-19患者的临床资料,及CT原始5 mm扫描图像和肺部高分辨0.63 mm重建图像。10例患者均行胸部CT检查,对其影像表现进行分析。结果9例患者为早期病变,1例为进展期病变。8例病灶累及双肺,2例累及单侧肺;病灶累及双肺各叶的比例差别不大;病灶多散在分布于各肺叶胸膜下8例;8例累及双肺病例中,6例一侧肺病变范围明显多于对侧;2例为纯磨玻璃密度病灶、2例为实性病变、6例均见磨玻璃密度影(GGO)和实变影;7例见充气支气管征;5例见条索影;2例小叶间隔增厚,呈“铺路石”征;10例均未见纵隔淋巴结肿大或胸腔积液。结论COVID-19具有一定的影像学特征,病灶在各肺叶分布较均匀,一般表现为双肺感染为主、多肺叶胸膜下受累的GGO和实变影,充气支气管征常见,纵隔淋巴结肿大或胸腔积液少见,CT检查对其诊断有着非常重要的作用。Objective To find the radiographic characteristics of COVID-19.Methods The clinical data of 10 COVID-19 patients were included in the study.High resolution chest CT images were recorded using a standard clinical protocol with 5 mm in plane resolution thickness and reconstructed thickness of 0.63 mm.All patients underwent chest CT scan,and the imaging features were analyzed.Results 9 patients were considered in early stage of the disease,1 patient was in the progressive stage.The lesions in 8 cases were found in bilateral lung,while other 2 cases were in unilatera lung.There was no obvious difference or unilateral changes in sizes of between two affected lung lobes.In 8 cases,the lesions mostly distributed under pleura area of each lung lobe.The lesions were evenly distributed in each lobe in cases with bilateral involvement,a nd appeared as pure ground-glass opacity(GGO)in 2 cases,consolidation in 2 cases,air bronchogram in 7 cases,fibrous stripes in 5 cases,GGO with consolidation in 6 cases.Crazy paving sign with interlobular septal thickening in 2 cases.In all 10 patients,there was no mediastinal lymphadenopathy or pleural effusion.Conclusion COVID-19 exhibits certain imaging characteristics on CT such as GGO or consolidation under pleura area with multiple lobes,and air bronchogram,but without mediastinal lymphadenopathy or pleural effusio.The lung lesions appear to evenly distribute in each lung lobe to some extent,and mainly in double-lung infection.CT plays an important role in the diagnosis of this disease.
