[Chinese expert consensus on the imaging diagnosis of severe pneumonia of influenza A (H1N1) flu].

In March 2009, influenza A(H1N1) flu broke out and spread rapidly worldwide, and it has been circulating in local areas with various scales since then. Particularly, the outbreak and prevalence have occurred in China during 2023 extensively. At present, there is an absence of unified consensus on imaging diagnosis of severe influenza A (H1N1) flu pneumonia, which is not conducive to the standardized imaging diagnosis and clinical practice. Chinese experts including the Infection and Inflammatory Radiology Committee of the Chinese Research Hospital Association jointly formulate this consensus based on numerous references related to influenza A (H1N1) flu, meanwhile combining the methodological requirements of evidence-based medicine for guideline and standard formulation. This consensus aims to form a consensus on the diagnostic evidence, recommended imaging methods, diagnostic standard and differential diagnosis of severe influenza A(H1N1) flu pneumonia, and it is ought to provide clear diagnostic information and basis for relevant professional physicians and guide the clinical diagnosis and treatment of severe pneumonia caused by influenza A(H1N1) flu.2009年3月甲型H1N1流感暴发并在全球范围内迅速蔓延，此后至今甲型H1N1流感仍在局部地区以不同规模流行，并于2023年期间在我国暴发流行。目前国内外缺乏甲型H1N1流感重症肺炎的影像学诊断的统一共识，不利于规范的影像诊断与临床治疗。中国研究型医院学会感染与炎症放射学专业委员会等国内专家在查阅与甲型H1N1流感相关的大量参考文献基础上，结合循证医学对指南及标准制定的方法学要求，共同制定本共识。本共识针对甲型H1N1流感重症肺炎的诊断依据，影像学方法，诊断标准以及鉴别诊断形成共识，旨在为相关专业医师提供明确的诊断信息及依据，指导甲型H1N1流感重症肺炎临床诊疗。.
