【摘要】 目的 :回顾性讨论 112例SARS患者急性期的胸部X线和CT表现特征。方法 :经临床诊断的SARS病例112例 ,男 4 3例 ,女 6 9例 ,年龄范围 16～ 82岁 ,平均年龄 35岁。所有患者在发病后 1周内均行胸部X线检查 ,2 2例同时行胸部CT扫描。结果 :112例患者在发病早期最常见的影像学表现为斑片状磨玻璃影 (胸片 79.5 %、CT81.8% )和磨玻璃影与不规则实变或肉芽肿样病变的混合影 (胸片分别为 2 1.4 %和 14 .%、CT分别为 4 5 .5 %和2 7.3%。病灶多位于中下叶 (70 .9% )并呈外周分布 (6 9% )。CT可见其他改变包括小叶内间隔和小叶间隔增厚(即碎石路样改变 ) (36 .4 % )、细支气管扩张 (18.2 % )和少量胸腔积液 (2 2 .7% )等。结论 :SARS急性期的X线和CT表现特征主要为 (1)不同类型的磨玻璃影伴有或不伴有实变或肉芽肿样病变 ;(2 )多累及双肺下叶和呈外周分布为主 ;(3)短期内演变迅速更多还原

【Abstract】 Objective: To retrospectively analyze the X ray and CT features of patients with suggestive of SARS at the early stages. Methods: The study comprised 112 patients (43 men,69 women; aged from 16 to 82 year) with clinically proved SARS. Chest radiograph was performed in all the patients and CT of thorax in 22 patients during the first week of the onset. Results: In the early stage, the most common findings were patchy ground glass opacification (GGO) (79.5% on X ray and 81.8% on CT) and mixed lesions of GGO with irregular consolidation (21.4% on X ray and 45.5% on CT) and/or granulomas (14.3% on X ray and 27.3% on CT). A majority of lesions were located in the middle and lower field (70.9%) with peripheral distribution (69%). Other findings on CT included intralobular and interlobular septal thickening (carzy paving pattern) (36.4%), bronchiectasis (18.2%) and small pleural effusion (22.7%). Conclusion: Common radiologic findings of SARS are ground glass opacification and mixed lesions of GGO with irregular consolidation and/or granulomas and lower location and peripheral distribution.更多还原
