【摘要】 目的 :探讨SARS死亡病例胸部X线及CT影像学表现 ,及其在诊断中的作用。材料和方法 :回顾性分析我院 11例符合SARS诊断标准的死亡病例的胸部X线平片和CT图像的表现及其特征。结果 :11例SARS死亡患者肺部阴影均较明显 ,为双侧多叶病变 ,病变面积占全肺组织的 80 %～ 90 % 6例 ,90 %以上 5例。病灶呈斑片及片絮状高密度影 8例 ,病变融合成大片实变阴影 8例 ,其中磨玻璃样改变 1例 ,肺内可见支气管充气像。结论 :X线及CT可清楚反映SARS病变的密度、形态和范围 ;并可了解其进展及转归 ,为临床诊断及治疗提供重要依据。更多还原

【Abstract】 Purpose:To identify features of SARS in its death cases with chest X-rays and CT. Materials and Methods: The manifestations of X-rays and CT of 11 death patients with SARS were analyzed retrospectively. Results: All patients showed local or multiple lesions of multilobes of bilateral lungs on chest x-rays and CT. The mean proportion of lesion area to the whole lung was 80-90% in 6 cases and over 90% in 5 cases. There were 8 cases in diffuse patchy shadow or shaggy cloudy shadow and one in ground-glass lesions and air bronchogram in the shadows. Conclusion: The density, shape and range of pulmonary lesions of SARS can be shown better by X-ray and CT.X-ray and CT has important value in ascertaining extent,and development stage of the lesion for the clinical diagnosis and treatment of SARS.更多还原
