摘　　要：目的:探讨CT对新型冠状病毒肺炎影像征象及动态变化。方法:收集我市2020年1月23日至2020年3月5日常规CT胸部扫描,经核酸检查确诊为新型冠状病毒肺炎的27例患者图像。分析其CT表现及随访动态变化。结果:病灶以肺外围背侧分布为主;长轴与胸膜平行为多见。病灶多见为多叶多灶分布斑片状病灶;病灶多数出现磨玻璃病灶。病灶内血管穿行清晰;也可表现为磨玻璃病灶与实性病灶共存,也可表现为实性病灶。结节伴晕征.铺路石征:表现磨玻璃密度内见多发细网格密度增高影,空气支气管征。病变沿着支气管间质分布。炎症病变使肺动脉增粗。病变先密度低逐渐增高,出现纤维变,再减低吸收。可出现此消彼长现象。结论:新型冠状病毒肺炎多累及双肺,表现形式多样,且影像演变迅速,有一定特征, CT可以清楚观察小病变及病变的变化。对临床治疗提供关键作用。Objective:To explore novel coronavirus pneumonia imaging signs and dynamic changes of CT. Methods:the novel coronavirus pneumonia was diagnosed by routine CT chest scan from January 23, 2020 to March 5, 2020 in our city, and 27 cases of new coronavirus pneumonia were diagnosed by nucleic acid examination. The CT manifestations and follow-up dynamic changes were analyzed. Results: the focus was mainly distributed on the dorsal side of lung periphery, and the long axis was parallel to pleura. Most of the lesions were multilobed and multifocal, and most of the lesions were ground glass. The blood vessels in the focus were clear, and the ground glass focus and solid focus coexisted, also the solid focus. Nodular with halo sign. Paving stone sign: multiple fine grid density increase shadow and air bronchogram sign are seen in the ground glass density. The lesions were distributed along the bronchial interstitium. Inflammatory lesions thicken the pulmonary arteries. At first, the density of the lesion was low and increased gradually, and then the absorption was decreased. This can happen. Conclusion:the novel coronavirus pneumoniae mostly involves two lungs, showing various forms, and the image evolves rapidly and has certain characteristics. CT can clearly observe the changes of small lesions and lesions. It provides a key role for clinical treatment.
