目的：探讨冠状病毒病2019 （COVID-19）不同临床类型患者的高分辨率计算机断层扫描（HRCT）初、随访表现。方法：选取川北医学院附属医院住院的7例新冠肺炎患者。所有患者均进行了初始和随访胸部HRCT检查。评估不同临床类型的主要CT表现及表征疾病严重程度的半定量评分。结果：初诊CT上，普通和严重病例的主要异常分别为纯磨玻璃影（GGOs）和GGOs周围的斑片状实变。危重病例多处实变，周围有大范围ggo分布于整个肺野。普通病例（4.5分和5分）、重度病例（9.5分和9.5分）和危重病例（19分和12分）的范围和密度评分呈梯度递增。随访CT表现为病灶密度降低、吸收实变、GGOs。危重病例显示病情恶化。普通和重症患者的程度评分和进展评分均显著降低，而危重症患者的范围评分最高，并伴有密度评分升高。结论：CT扫描可准确评估COVID-19的严重程度，并有助于监测不同临床情况随访期间的疾病转化情况。
OBJECTIVE: To discuss the high resolution computed tomography (HRCT) manifestations of coronavirus disease 2019 (COVID-19) patients among different clinical types on initial and follow-up CT.METHODS: Seven COVID-19 patients admitted to the Affiliated Hospital of North Sichuan Medical Collage were enrolled. All patients underwent initial and follow-up chest HRCT. The main CT features and semi-quantitative score which represent disease severity among different clinical types were evaluated.RESULT: On initial CT, the main abnormalities observed in common and severe cases respectively were pure ground glass opacities (GGOs) and patchy consolidation surrounded by GGOs. Critical cases had multiple consolidation surrounded by wide range of GGOs distributed in the whole lung fields. The scope and density score in common (4.5 and 5), severe (9.5 and 9.5) and critical (19 and 12) cases were increased by gradient. On follow-up CT, common and severe types manifested as decreasing density of lesion, absorbed consolidation and GGOs. Critical cases showed progression of the disease. The extent and progression scores in common and severe patients were significantly decreased, while the range score of patients with critical disease reached the highest points, accompanied with an increase in the density score.CONCLUSION: CT scanning can accurately assess the severity of COVID-19, and help to monitor disease transformation during follow-up among different clinical conditions.
