摘　　要：目的 探讨甲型H1N1流感的胸部影像表现.方法 对13例临床确诊的甲型H1N1患者的胸部X线和CT的影像征象进行分析.结果 甲型H1N1流感的胸部X线和螺旋CT影像征象主要表现为两肺的磨玻璃状与实变共存或磨玻璃状影,病变以两下肺及周围分布为主,实变的肺组织内可见支气管气像.13例中9例病变分布超过3个肺叶.2例显示边界不清的磨玻璃状小结节.2例在磨玻璃状病变中可见空腔.2例X线平片仅显示慢性支气管炎的异常征象.多层螺旋CT扫描于磨玻璃状密度、磨玻璃状密度与实变共存肺组织中可见明显的肺间质增厚.结论 胸部X线和多层螺旋CT检查对于甲型H1N1流感病人的诊断有重要作用,HRCT是显示病变分布和肺间质改变的首选检查方法.Objective To evaluate the chest imaging features of influenza A H1N1. Methods Chest X-ray and CT imaging features in 13 patients with influenza A H1N1 comfirmed clinically were analysed. Results The most common radiographic and MSCT findings in patients with influenza A H1N1 were ground--glass opacities （GGO） associated with muhifocal areas of consolidation and air bronchogram,or only GGO in bilateral lungs and most with lower and peripheral distribution. The lesions involving over 3 lobes of lung were seen in 9/13 patients. Two patients showed ill-defined GGO nudules. Two patients showed air-space in GGO regions. Two patients had no more radiographic appearance except for chronic bronchitis. On MSCT,GGO and areas of consolidation had a predominant peribronchovascular. Conclusion X-ray and MSCT of the chest is important in diagnosis of influenza A H1N1, HRCT is the first examination for showing the disposition of process and changes of the pulmonary interstitium.
