目的分析CT诊断小儿肺炎支原体肺炎的临床应用价值。方法回顾性分析500例经病理学诊断为小儿肺炎支原体肺炎患儿临床资料,所有患儿均分别接受CT及X线检查,比较两种诊断方法的临床效果。结果 500例小儿肺炎支原体肺炎患儿中,CT检查确诊451例,CT检查小儿肺炎支原体肺炎的确诊率为90.2%;X线检查确诊325例,X线检查小儿肺炎支原体肺炎的确诊率为65.0%,CT检查诊断小儿肺炎支原体肺炎确诊率明显高于X线检查,比较差异具有统计学意义(P<0.05)。本组500例患儿中,CT与X线检查影像学结果均为肺组织实变。其中,X线检查影像学主要表现为间质浸润型,在影像学上可表现为肺纹理增加、增粗,且具有边缘不够清楚等特征,部分患儿为混合型表现,也有患儿为腺泡型。CT检查影像学主要表现为不均匀高密度影,少部分患儿合并肺不张,部分患儿合并胸腔积液。结论与X线诊断方法相比,CT诊断小儿肺炎支原体肺炎,病灶图像更加清晰,且诊断准确率较高,更具临床应用价值,值得推广。
Objective To analyze the clinical value of CT in diagnosis of Mycoplasma pneumoniae pneumonia in children. Methods The clinical data of 500 children diagnosed as Mycoplasma pneumoniae pneumonia by pathology were retrospectively analyzed. All the children underwent CT and X-ray examination. The clinical effects of the two diagnostic methods were compared. Results Among the 500 cases of children with mycoplasma pneumoniae pneumonia, 451 cases were diagnosed by CT, 90.2% were confirmed by CT, and 325 cases were diagnosed by X-ray. The diagnosis of Mycoplasma pneumoniae pneumonia was 65.0% The diagnosis rate of mycoplasma pneumoniae pneumonia in CT diagnosis was significantly higher than that of X-ray examination, the difference was statistically significant (P <0.05). The group of 500 children, CT and X-ray imaging results are lung consolidation. Among them, the X-ray examination imaging mainly for interstitial infiltration type, the image can be expressed as increased lung markings, thickening, and the edge is not clear enough and so on, some children with mixed performance, but also children with glandular Bubble CT imaging showed mainly uneven high-density imaging, a small number of children with atelectasis, some children with pleural effusion. Conclusion Compared with X-ray diagnosis, CT diagnosis of children with Mycoplasma pneumoniae pneumonia, the lesion image more clearly, and the diagnosis of high accuracy, more clinical value, it is worth promoting.
