摘　　要：目的探讨高致病性禽流感的肺部床头胸片及CT表现。方法报告6个病例,6例治愈,均为确诊病例。回顾性分析其肺部影像表现。结果肺部病变主要的影像学特点为:1.床头胸片为弥漫性肺实变和间质改变以及进展迅速,变化快,吸收缓慢。病变早期以双肺斑片状渗出为主,随后迅速扩大,后期表现为两肺弥漫性实变;病变吸收缓慢,先为渗出病灶,且肺部纤维化病灶的吸收持续时间长。结论胸部X线检查是发现H5N1高致病性禽流感最基本的影像学检查方法,可显示病变密度、形态和范围以及变化情况,有助于判断病情,指导治疗和估计预后。Objective Investigate the Pulmonary imaging appearances of highly pathogenic avian influenza A by thorax X-ray and CT scanning.Methods reported 6 cases,6 patients were cured,they were confirmed cases.Lung imaging performances were retrospectively analyzed.Results The main imaging lung disease is characterized：Bedside thorax X-ray shows diffused lung consolidation and interstitial changing,it changes and progresses rapidly,absorption is slow.Early Pulmonary lesions mainly patchy exudation followed by the rapid expansion,late stage shows diffuse lung consolidation;lesions absorption is slow,exudative lesions appear firstly,and the absorption of lung fibrosis lesions last long time.Conclusion thorax X-ray detection of the highly pathogenic avian influenza（H5N1） is the most basic imaging method which can show lesions density,shape and scope,it help to determine the patients condition and guide the treatment and estimate the prognosis.
