目的探讨新生儿肺炎的影像学特征。方法 46例新生儿肺炎患儿的CT、胸X线平片以及临床资料。结果 X线检查主要表现为肺纹理异常、点状或片状密度增高影等,部分合并肺部或支气管充气征、局部肺不张等;CT主要表现为斑片状高密度影,病灶中心密度较周围密度明显增高,且边缘较为模糊,同时存在肺不张以及局限性肺气肿等。X线诊断准确率为67.4%,低于CT检查的87.0%,差异有统计学意义(P<0.05)。结论 X线平片与CT检查对新生儿肺炎具有一定的特异性表现,两种方法联合应用可提高临床诊断准确率。
Objective To investigate the imaging features of neonatal pneumonia. Methods 46 cases of neonatal pneumonia in children with CT, chest X-ray and clinical data. Results X-ray examination showed abnormalities of the lungs, increased density of punctate or sheet densities, partial pulmonary or bronchial insufflation, and local atelectasis. CT mainly manifested as patchy high density, focal density Significantly higher than the surrounding density, and the edge is more vague, with the presence of atelectasis and limited emphysema. The diagnostic accuracy rate of X-ray was 67.4%, which was lower than that of CT examination (87.0%), the difference was statistically significant (P <0.05). Conclusion X-ray and CT examination of neonatal pneumonia have a certain specificity, the combination of the two methods can improve the accuracy of clinical diagnosis.
