【摘要】 目的 :探讨胸部CT在SARS诊断中的研究现状。方法 :综述近期国内外有关SARS胸部CT研究资料。结果 :CT可明显提高肺内SARS小病灶及间质纤维化的显示 ,特别是薄层CT或HRCT。SARS的CT基本影像表现为磨玻璃样密度影像和肺实变影像。根据CT影像表现 ,可将SARS分为发病早期 ,进展期和恢复期。各期具有不同的动态影像表现和相应的肺实质及肺间质病理改变。结论 :胸部CT在SARS诊断中是确定诊断和病情观察的重要方法。在SARS特异性IgM和IgG抗体尚待结果 ,病毒颗粒未分离出之前 ,更具有特殊意义。更多还原

【Abstract】 Objective:To study the current condition on chest CT appearance in patients with SARS.Methods:Summarizing the present data on chest CT in SARS home and abroad.Result: CT may further pick out pulmonary small lesions and fibrosis in SARS, especially HRCT or thin-CT. Basic imaging feathers of CT in SARS included ground-glass opacities and pulmonary consolidation. SARS was divided into early phase, progressive phase and obsorbing phase by the CT imaging. There were different dynamic imagings in different phases and respectively pathology changes of pulmonary parenchyma and interstitial. Conclusion: Chest CT was important method of diagnosing and obversing courses of disease in SARS. It plays an important role prior to specific IgM and IgG in SRAS and isolated SARS-CoV.更多还原
