摘要
目的:探讨甲型H1N1流感胸部多层螺旋CT的表现特征。方法:50例甲型H1N1流感的患者,均行胸部CT检查,回顾分析其CT表现,将患者为分两组。结果:组1(28例)和组2(22例)的患者胸部薄层CT检查均为异常。本病的影像学特征为:病变以累及双肺下叶为主,异常表现为磨玻璃密度病变(ground-glass opacity,GGO)伴有或者不伴有局限性的肺实变,磨玻璃阴影的分布特征为中轴区域(沿支气管血管束)或外周区域的多中心性分布,形态特征为类圆形或斑片状。结论:甲型H1N1流感与肺部其它病变的CT表现虽然部分有交叉相似之处,但甲型H1N1流感的CT表现有其特征性,并且结合流行病史、临床、实验室检查等对本病的诊断和治疗有指导性意义。
Objective：To retrospectively analyze the multi-slice spiral computed tomographic（MSCT） features in patients with swine-origin influenza A（H1N1） virus（S-OIV） infection.Methods：50 patients with symptoms and signs suggestive of S-OIV infection underwent CT of the thorax.The patients were sorted into two groups.Results：Thin-section CT scans were abnormal patients in groups 1 and 2.Common thin-section CT features of swine-origin influenza A（H1N1） viral infection are peripheral ground-glass opacification or mixed ground-glass opacifjication and consolidation.Although all segments of the lung can be involoved,affected segments were predominantly in the lower lobes.In terms of location within a lung segment,the lesions tended to be peripheral or both central and peripheral.Conclusion：There are same image characteristics of lesions at thin-section CT between S-OIV infection and others.CT examinations is very important application value of diagnosis and clinical treatment on S-OIV infection when it combinate the epidemiologic,the clinical laboratory examinations.
