新型冠状病毒肺炎影像学辅助诊断指南

Guideline for medical imaging in auxiliary diagnosis of coronavirus disease 2019

自2019年12月发生新型冠状病毒肺炎(COVID-19)疫情后,国家卫生健康委员会组织相关专家制定了《新型冠状病毒感染的肺炎诊疗方案(试行第一至六版)》,将具有特征性肺部影像学改变的疑似患者纳入临床诊断病例。肺部影像学检查主要以胸部CT[尤其是高分辨率CT(HRCT)]为主、胸部X线片为辅。目前国内外影像学专家已针对COVID-19形成共识,即胸部HRCT(层厚≤1.0 mm)是当前筛查与诊断COVID-19的主要手段之一,突出了胸部CT作为临床循证诊断COVID-19指标的重要性。本指南由中国研究型医院学会感染与炎症放射学专业委员会主导,中国性病艾滋病防治协会感染(传染病)影像工作委员会、中华医学会放射学分会传染病学组、中国医师协会放射学分会感染影像专业委员会、中国医院协会传染病分会传染病影像学组、中国装备协会普通放射装备专业委员会传染病学组、北京影像诊疗技术创新联盟等精英专家团队协同制定,将进一步提升广大医务工作者对于HRCT在影像学诊断COVID-19及疗效观察中的价值的认识,理解流行病学、临床指标、实验室指标及CT影像学指标之间的互补关系,利于客观进行临床诊断。

Since the outbroke of coronavirus disease 2019(COVID-19)in December 2019,the National Health Commission has organized experts to develop the"Novel Coronary Viral Infection Pneumonia Diagnosis and Treatment Program"pilot version from the first to sixth edition,emphasizing that suspected COVID-19 patients with characteristic chest CT findings should be regarded as clinical diagnosed cases.The consensus has formed that CT,especially high resolution CT(HRCT)is the main imaging method,supplemented by X-ray for chest imaging examinations,which highlights the critical role of chest CT in clinical diagnostic indicators for evidence-based diagnosis of COVID-19.This guideline is led by the Radiology Committee on Infectious and Inflammatory Disease,Chinese Research Hospital Association,in collaboration with the Radiology of Infection Branch,Working and Treating committee of HIV/AIDS and STD Association,the Radiology of Infection Sub-branch,Radiology Branch,Chinese Medical Association,the Committee on Radiology of Infection,Radiologist Branch,Chinese Medical Doctor Association,the Radiology of Infectious Disease Management Sub-branch,Infectious Disease Management Branch,Hospital Management Association in China,the Infectious Disease Group,General Radiology Equipment Committee,China Association of Medical Equipment and the Beijing Imaging Diagnosis and Treatment Technology Innovation Alliance.The formulation of the guideline will enhance the understanding of diagnostic and therapeutic value of HRCT in COVID-19 and grasp the epidemiology,clinical,laboratory and CT imaging indicators for correct diagnosis.
