摘要
目的:观察分析新型冠状病毒(2019 novel coronavirus, 2019-nCoV)肺炎(新冠肺炎)患者的CT表现,探讨CT在诊断中的价值。方法:回顾性收集2020年1月20日至2月10日在上海交通大学医学院附属瑞金医院和瑞金北院发热门诊就诊者,患者依据实时荧光反转录聚合酶链反应(reverse transcription-polymerase chain reaction,RT-PCR)检测核酸结果阳性而确诊,分析所有患者的临床资料、首次实验室检查和CT图像。结果:确诊为新冠肺炎的病例共有12例,发病1周内CT检查结果显示,所有患者均有肺部浸润,累及多个肺叶和肺段。12例患者的病灶CT征像均表现为磨玻璃影(ground glass opacity,GGO),外周带多见,其中8例出现GGO合并片状实变;10例患者的病灶内伴有局灶性网格影;9例病灶内出现空气支气管征;未见纵隔淋巴结肿大和胸腔积液。结论:新冠肺炎患者发病1周内,CT图像上多表现为多灶性、斑片状、外周分布为主、两肺下叶多见的GGO。疫情爆发期间,如果在CT影像上发现GGO多于实变时,应高度怀疑新型冠状病毒感染。CT检查结果对早期治疗和及时隔离至关重要。
Objective: To analyze the CT features of patients with 2019 novel coronavirus(2019-nCo V) pneumonia,and explore the value of CT examination in the diagnosis. Methods: The clinical data of patients with fever and 2019-nCoV detected by real-time fluorescence RT-PCR from January 20 through February 10, 2020 were retrieved and imaging findings on CT were retrospectively reviewed. Results: Of all 12 patients with 2019-nCoV pneumonia, all had pulmonary infiltrations, involving multiple lung lobes and segments. Lesions on CT image showed GGO in all patients(12/12), pre-dominantly located in the peripheral zone, with local reticular pattern within GGO and air bronchogram identified in 10 and 9 cases respectively. The patchy consolidation accompanying GGO presented in 8 cases. The lymphadenopathy and pleural effusion, however, were absent in all patients. Conclusion: For patients with novel coronavirus pneumonia within the first week of illness, the multifocal and patchy peripheral pure GGO, predominantly in the lower lung,is the most com-mon findings on CT images. The extensive GGO with mild consolidation on CT scans is highly suspicious of 2019-nCoV infection and may prompt early treatment and prompt isolation in early outbreak.
