【摘要】 目的 观察分析严重急性呼吸综合征(SARS)病程中胸部影像动态改变特征。方法 收集北京胸科医院2003年3月27日～5月27日确诊的资料较完整的SARS患者病例86例。回顾性分析这些影像资料，观察其在病程不同时期的影像动态改变特征。结果 86例临床确诊病例胸部X线出现异常的时间多在发病的4～7天

    (73.3%)，初期最常见的胸部X线异常表现为斑片状模糊影，单侧53例(61.6%)，双侧33例(38.4%)。病程极期的时间多在8～14天(74.4%)，病变的主要特点是进展速度较快的单发或多发大片状模糊影(81.4%)，部分患者病变呈游走性改变。病变大多分布于中、下肺野为73例(84.9%)。多数病变吸收的时间为15～21天(48.8%)。CT对病变的观察更为敏感。结论 SARS患者胸部X线表现在疾病的不同阶段有一定的特点，影像的动态改变对指导治疗起着至关重要的作用。

    【Abstract】 Objective To observe the chest image features and mobile changes of SARS cases.Methods To observe the chest image features in the different time of the disease stages of 86 clinical diagnosed SARS cases hospitalized during 27，March to 27，May 2003. Results In most cases (73.3%)，the chest X-ray changes appeared in the 4th～7th day. At the early stage，most patient's X-ray showed mottling shadow in one side (61.6%) or both sides (38.4%) of the lung. The most severe stage of the disease in most cases (74.4%) occurred on the 8th～14th day. The X-ray appearance in this stage showed progressing uni- or bilateral patchy shadows in most cases (81.4%) and in some cases the changes was migrating. The X-ray changes were usually seen in the middle or lower lung field in 73 cases (84.9%). In majority cases (51.39%) ......
