%X 摘要 目的　探讨2019新型冠状病毒肺炎（COVID-19）的CT表现特点及诊断价值。 方法　回顾性分析我院及外院30例经《新型冠状病毒感染的肺炎诊疗方案》确诊患者的CT图像,主要观察指标包括病变部位、数目、形态、密度以及疾病进展的CT表现。 结果　30例患者中CT表现为双肺多发性病变21例（70.0%），同时累及2个及以上肺叶22例（73.3%），病变累及肺下叶24例（80.0%），累及肺上叶20例（66.7%），累及右肺中叶15例（50.0%）。所有病变以肺外带最多见（22例）。病变呈片状磨玻璃样密度影(GGO)23例（76.7%），片状实变影10例（33.3%），片状GGO合并肺片状实变影7例（23.3%），片状GGO或者肺实变影合并纤维条索样影7例（23.3%）。无肺门、纵膈淋巴结肿大及数目增多，未见胸腔积液和心包积液。入院后16例（53.3%）患者CT检查随访评估病情变化，其中病变进展12例（75.0%），片状GGO或磨玻璃样结节影(GGN)数量增加、范围扩大或逐渐实变12例（75.0%），片状肺实变影范围增大、密度不均匀增加7例（43.8%）,病变好转2例（12.5%）。 结论　COVID-19患者CT表现病变以双肺中下叶外带多见，早期以局限片状GGO为主，进展期病变范围增大，密度增高，呈实变样改变。同一时期可同时存在不同类型病变。病变变化较快。CT检查可清楚反映病变部位、分布、密度、形态和范围的变化，在早期诊断和了解病变的动态变化等方面具有重要价值。<br>Abstract：Objective　To investigate the CT features of coronavirus disease 2019 (COVID-19) and their diagnostic value. Methods　A retrospective analysis was performed for the CT images of 30 patients with COVID-19 who were diagnosed in our hospital and other hospitals according to Guidelines on the Novel Coronavirus-Infected Pneumonia Diagnosis and Treatment, and major observation indices included the location, distribution, number, morphology, and density of lesion and CT findings of disease progression. Results　Among the 30 patients, 21(70.0%) had the CT manifestation of multiple lesions in both lungs, 22(73.3%) had the involvement of two or more lobes, 24(80.0%) had the involvement of the inferior lobe of the lung, 20(66.7%) had the involvement of the superior lobe of the lung, and 15(50.0%) had the involvement of the middle lobe of the right lung. Most lesions were located in the extrapulmonary area (22 patients). Of all patients, 23(76.7%) had patchy ground-glass opacity (GGO), 10(33.3%) had patchy consolidation, 7(23.3%) had patchy GGO with pulmonary consolidation, and 7(23.3%) had patchy GGO or pulmonary consolidation with fibrous stripes. No lymph node enlargement was observed in the pulmonary hilum or mediastinum, and no pleural effusion or pericardial effusion was observed. CT examination was performed for 16 patients (53.3%) after admission, among whom 12(75.0%) experienced disease progression, 12(75.0%) had increased number and extent or gradual consolidation of patchy GGO or ground glass nodules (GGN), 7(43.8%) had increased extent of patchy pulmonary consolidation or uneven increase in density, and 2(12.5%) achieved improvement of the disease. Conclusion　The lesions of COVID-19 are mostly located in the periphery zone of the middle and lower lobes of lungs; local patchy GGO is often observed in the early stage, while increased extent and density and consolidation are observed in disease progression.
