| 摘 要： | 目的:总结新型冠状病毒肺炎(2019-nCoV)的X线、CT表现,为临床提供影像学诊断依据。材料与方法:收集2020年1月21日至2月25日我院发热门诊的1028例患者,均进行X线检查,其中18例核酸检测确诊为2019-nCoV,6例同日行CT检查,9例于1周内进行影像学复查。结果:18例确诊的2019-nCoV患者,4例X线表现为肺纹理增重,14例X线表现为肺内单发或多发病灶。好发部位为肺下叶,单侧肺下叶病灶9例,双肺下叶病灶3例,双下肺合并双肺上叶病灶2例。6例同日进行CT检查,1例CT正常,3例发现X线胸片未显示的小片状磨玻璃影,2例CT显示的病灶较X线片多,CT表现以双肺胸膜下分布为主,可伴空气支气管征且小叶间隔增厚。6例患者1周内复查X线片,3例复查CT,其中1例CT显示磨玻璃影吸收,8例显示病变进展,范围较前增大和病灶增多,以双下肺外带为著。结论:新冠肺炎胸部X线及CT表现具有一定的特征性,结合临床病史和实验室检查可作出明确诊断。

| Abstract: | Purpose:We make a summing up of the X-ray and CT findings of patients infected with the 2019 novel coronavirus(2019-nCoV). Materials and methods:A total of 1028 patients with fever in fever clinic of our hospital from January 21, 2020 to February 25, 2020 were done X-ray examination. Among them, 18 cases were confirmed to be 2019-nCoV by nucleic acid detection, 6 patients underwent CT examination on the same day, and 9 patients underwent imaging review within 1 week. Result:Among the 18 patients confirmed with 2019-nCoV, 4 patients X ray presented with increase of lung markings, 14 patients X ray presented with single or multiple lung lesions. The preferred location of lung lesion was the lower lobe. 9 patients presented with unilateral lesions in the lower lobe of the lung, 3 patients showed bilateral lesions in the lower lobe of the lung, and the other 2 patients presented with bilateral lesions in the upper and lower lobe of the lung. Six patients underwent CT examination on the same day and ground glass opacities were found in 3 cases that X-ray chest film did not show before. The CT findings of 1 case were normal. In 2 cases, CT showed more lesions than X-ray. The predominant pattern of CT findings of patients with 2019-nCoV infections include bilateral ground-glass opacities of the subpleural lung, air bronchograms and interlobular septal thickening. X-ray films were reviewed in 6 patients within 1 week, and CT was reexamined in 3 patients, among which 1 patient showed ground glass shadow absorption on CT, 8 patients showed lesion progression than before with double lower lobes of lung involved. Conclusion:The chest X-ray and CT manifestations are of certain characteristics in 2019-nCoV, combined with the clinical history and laboratory examination the diagnosis may be done. |
