| 摘 要： | 目的：探讨新型冠状病毒肺炎（COVID-19）的胸部CT表现，进行CT评分和分期。资料与方法：回顾性分析上饶市104例确诊的COVID-19患者胸部CT图像，包括病变累及范围、分布模式、形态及密度等特点，并对病灶累及范围进行半定量评分。结果：88例患者胸部CT见异常表现，累及两个及以上肺叶的有74例（72%），病灶以外周/胸膜下分布为主（60例，58%）。CT表现为单纯磨玻璃影的有29例（28%），53例（51%）为磨玻璃及实变混合影，其内部常见网格影（32例，31%）和增粗血管（33例，32%）。仅有两患者见胸腔积液，无一例见肺空洞及增大淋巴结。CT评分显示纳入的病例≤5分的有84例（81%），6~10分的有16例（15%），11~15分的有4例（4%），无一例≥16分。结论：COVID-19的胸部CT表现具有一定特征性，CT半定量评分对评估病情有较大价值。

| Abstract: | Objective:To investigate the chest CT manifestations of novel coronavirus pneumonia(COVID-19), and to perform CT scoring and staging. Materials and Methods:Chest CT images of 104 confirmed COVID-19 patients in Shangrao were retrospectively analyzed, including lesion involvement range, distribution pattern, morphology and density, and semi-quantitative scoring of lesion involvement range. Results:The chest CT of 88 patients was abnormal, 74 patients(72%) involved two or more lung lobes, 60 patients(58%) had a peripheral distribution of disease. There were 29 patients(28%) who showed pure ground-glass, 53 patients(51%) demonstrated ground-glass and consolidation, the internal grid(32 patients, 31%) and thickened blood vessel were common(33 patients, 32%). Pleural effusion was seen in only two patients, and no cases were seen with cavitation and enlarged lymph nodes. CT scores were obtained for all patients,84 patients scored 5 or less, 16 patients(15%) scored 6-10, 4 patients(4%) scored 11-15, and none scored 16 or more. Conclusion:The chest CT of COVID-19 have some characteristic manifestations,and the CT semi-quantitative score is of great value in assessing the condition. |
