目的：探讨新型冠状病毒肺炎（NCP）胸部CT图像特点及临床价值。 材料与方法：收集80例NCP患者的临床资料及CT图像。分析患者的临床表现和实验室检查结果。对患者胸部 CT 图像中每个肺段的病变进行了表征。根据病灶长度和扩散程度进行评分。结果：主要临床表现为发热、干咳、乏力、少量白痰或腹泻。在80名患者的第一张胸部CT图像中，总共发现了1,702个评分病灶。病变主要位于肺部胸膜下区（92.4%）。大多数病变为磨玻璃样混浊，随后的融合范围可能扩大，主要在胸膜下区域扩散。肺实变占所有病变的44.1%。 80例患者中，76例（95%）有双侧肺部病变，4例（5%）有单侧肺部病变，8例（10%）有条索状阴影。结论：NCP患者胸部CT表现为双侧毛玻璃病灶起病，位于肺部胸膜下区，病灶进行性进展，最终实变，无游走性病灶。胸腔积液和纵隔淋巴结肿大很少见。由于患者早期核酸检测阴性的同时也可能出现肺部炎症改变，胸部CT结合流行病学和实验室检测是评估疾病和疗效的有用检查。 (C) 2020 年皇家放射科医生学院。由爱思唯尔有限公司出版
AIM: To investigate the characteristics and clinical value of chest computed tomography (CT) images of novel coronavirus pneumonia (NCP).MATERIALS AND METHODS: Clinical data and CT images of 80 cases of NCP were collected. The clinical manifestations and laboratory test results of the patients were analysed. The lesions in each lung segment of the patient's chest CT images were characterised. Lesions were scored according to length and diffusivity.RESULTS: The main clinical manifestations were fever, dry cough, fatigue, a little white sputum, or diarrhoea. A total of 1,702 scored lesions were found in the first chest CT images of 80 patients. The lesions were located mainly in the subpleural area of the lungs (92.4%). Most of the lesions were ground-glass opacity, and subsequent fusions could increase in range and spread mainly in the subpleural area. Pulmonary consolidation accounted for 44.1% of all of the lesions. Of the 80 cases, 76 patients (95%) had bilateral lung disease, four (5%) patients had unilateral lung disease, and eight (10%) patients had cord shadow.CONCLUSION: The chest CT of NCP patients is characterised by the onset of bilateral ground-glass lesions located in the subpleural area of the lung, and progressive lesions that result in consolidation with no migratory lesions. Pleural effusions and mediastinal lymphadenopathy are rare. As patients can have inflammatory changes in the lungs alongside a negative early nucleic acid test, chest CT, in combination with epidemiological and laboratory tests, is a useful examination to evaluate the disease and curative effect.
