| 目的 分析非典型肺炎和典型肺炎的胸部X线征象,为鉴别诊断提供依据。方法 采用回顾性对比分析非典型肺炎和典型肺炎的发病年龄、病灶进展速度、不同时期肺内病灶的分布和形态特征。结果 非典型肺炎好发中青年,发病与性别无关(P>0.05),两组早期病灶多位于下肺野,病灶形态以肺纹理增强、斑片状分布为主,两者比较无显著差异(P>0.05);非典型肺炎48h内病灶扩展速度大于50%患者多于典型肺炎(P<0.05),非典型肺炎高峰期病灶多数累及双肺,病灶形态呈毛玻璃样变为主(P<0.05),典型肺炎以单侧为主,病灶形态以片状为主(P<0.05),非典型肺炎吸收较典型肺炎缓慢。结论 认识病灶扩展速度和高峰期病灶累及范围及形态,有利于区分非典型肺炎和典型肺炎。 |

| Objective To differentiate typical pneumonia and SARS.Methods A retrospective study on the results of chest radiographic fingdings was carried out in 103 SARS patients and 90 typical pneumonia patients.The distribution of focus,as well as its shape and progress,were investigated in the stages of occurrence,development,distribution and absorption.Results SARS patients were younger than typical pneumonia patients,the diffenrence was significant (P<0.05).In the early stage of both typical pneumonia patients and SARS,focus located in the lower lobes showed lung markings enhangcement or opaquw-like shadows,the diffenrence was not significant (P>0.05).In most severe stage of SARS,the lesions distributed bilaterally in the lung,shadows were ground-glass-like.But in typical pneumonia patients,the lesions distributed unilaterally,shadows were large opaquw-like,the diffenrence was significant (P<0.05).Completly absorption process in SARS was longer than typical pneumonia.Conclusion The characterized features and evolvement of chest radiographs can help to differentiate SARS and typical pneumonia. |
