摘　　要：目的探讨新型冠状病毒肺炎(COVID-19)的HRCT表现、分期及病程转归变化。方法收集27例COVID-19确诊病例的临床、首次及多次CT复查影像学资料,并进行回顾性分析。结果COVID-19首次CT检查影像学特点主要表现为两肺多发26例(96.3%),左肺下叶单发1例(3.7%);病灶位于胸膜下25例(92.6%),内中带2例(7.4%);磨玻璃影27例(100%),小叶间隔增厚26例(96.3%),磨玻璃影内含实性成分7例(25.9%),磨玻璃影内可见血管增粗10例(37.0%);典型“铺路石征”20例(74.1%);支气管充气征13例(48.1%),其中支气管壁增厚12例(44.4%);“晕征”15例(55.6%)。27例中初诊CT早期9例(33.3%),进展期17例(63.0%),消散期(或恢复期)1例(3.7%),复查CT重症期表现3例(12.5%)。结论HRCT对诊断COVID-19、判断疾病分期及病程转归具有重要价值。Objective To investigate the novel coronavirus pneumonia(COVID-19)HRCT findings,staging and prognosis.Methods The clinical,baseline and multiple follow-up CT imaging data of 27 cases confirmed infection by COVID-19 were collected and analyzed retrospectively.Results The imaging features of the baseline CT examination of COVID-19 weremultiple lesions in two lungs(96.3%),single lesion in the left lower lobe(3.7%);the lesions were located at the subpleura among 25 cases(92.6%),at themedial zone among two cases(7.4%).The results showed ground glass opacity among 27 cases(100%),interlobular septal thickening among 26 cases(96.3%),solid components in ground glass opacity among seven cases(25.9%)and"vascular thickening"in ground glass opacity among ten cases(37.0%),and 20 cases(74.1%)were typical with"crazy-paving"pattern,13 cases(48.1%)with air-bronchogram sign,12 cases(44.4%)with bronchial wall thickening,15 cases(55.6%)with halo sign.Among the 27 cases of the baseline CT scan,nine cases(33.3%)were diagnosed in the early stage,13 cases(63.0%)in the advanced stage,one case(3.7%)in the dissipation stage(or recovery stage),and 3 cases(12.5%)in the severe stage during the follow-up.Conclusions HRCT plays an important role in the diagnosis of COVID-19 and the evaluation of stage and course.
