CT对新型冠状病毒肺炎的诊断价值

The Diagnostic Value of CTin Novel Coronavirus Pneumonia

目的:分析总结新型冠状病毒肺炎胸部CT的影像表现,为临床诊断、治疗及预后评估提供重要依据。方法:回顾性分析2020年1月28日-2月16日鄂州市中心医院经RT-PCR检测显示2019-nCoV核酸检测阳性的73例新冠肺炎患者临床及影像学资料。结果:男性39例,女性34例,年龄24~81岁,胸部CT检查结果均为阳性,病灶多分布于两肺野外带胸膜下,两肺下叶最易受累,片状及云絮状磨玻璃样密度最为常见,可合并实变,40例同时累计5个肺叶,空气支气管征及铺路石征较为多见,胸腔积液及气胸少见;CT短期随诊影像变化迅速,15~30d肺内病灶吸收好转明显。结论:新型冠状病毒肺炎CT具有一定特征性表现,对临床诊断、治疗及预后评估有着重要的参考价值。

Objective: The CT findings of the new coronavirus pneumonia were analyzed and summarized to provide important basis for clinical diagnosis, treatment and prognosis evaluation. Methods: The clinical and imaging data of 73 patients with new coronavirus pneumonia who tested positive for 2019-nCoV nucleic acid by RT-PCR in the hospital from 28 th January 2020 to16 th February 2020 were retrospectively analyzed. Results: There were 39 males and 34 females, aged 24-81 years old, whose results of chest CT examination were positive. The lesions were mostly distributed under the pleura in the field of both lungs. The lower lobes of the lungs were the most vulnerable. The flake and cloud-like ground-glass density were the most common, and might be combined with consolidation. In 40 cases, 5 lung lobes were accumulated at the same time. Air bronchial signs and paving stone signs were more common, while pleural effusion and pneumothorax were rare. CT short-term follow-up images changed rapidly, and the absorption of lung lesions improved significantly after 15-30 d. Conclusion: CT of the novel coronavirus pneumonia has certain characteristics, which is of important reference value for clinical diagnosis, treatment and prognosis evaluation.
