摘要
目的 :研究SARS影像学的新进展。方法 :阅读国内外有关文献并进行综述。结果 :X线胸片显示单侧或双侧局灶性斑片状模糊影 ,然后迅速扩大到其他肺野 ,部分呈片团状弥漫分布 ,部分融合呈大片状 ,中心密度高 ,周边密度低 ,可见支气管气像。CT表现两肺大部或弥漫磨玻璃样改变 ,肺间质增厚 ,呈粗大网状 ,夹杂斑块状肺实变影 ,随访检查 ,影像学动态改变迅速。结论 :SARS胸部影像改变多种多样 ,如结合流行病学史 ,临床表现 ,实验室检查及影像学资料将能作出正确诊断。
Objective:To investgate the new progress of SARS imaging.Methods:Reading the literatures home and abroad,then summarizing.Results:On roentgenography,the main abnormality was unilateral or bilateral localized patchy clouding opacity.The opacity progressed quickly into other parts of lung over time.The lesion developed into bilateral diffuse opacity involving most of the lung in the fully advanced phase.Some lesion presented as diffuse small patches while some other lesion as fused large patches with high density in the center and low density in the peripheral regions associated with air bronchium sign.CT finding showed frosted-grass changes and interstitial thickening mesh appearance and consolidation,The follow-up results showed rapid imaging chang.Conclusion:The chest imaging in SARS varies,The combined use of the epidemiologic history,clinical situation,laboratory tests and imaging examinations can make a difinite diagnosis.
