新生儿肺透明膜病X线片与CT诊断对照分析

Comparative analysis of hyaline membrane disease with X-ray films and CT diagnosis

目的对新生儿肺透明膜病X线片和CT诊断结果进行比较分析，并探讨其应用。方法选取2009年11月～2011年11月于我院诊治的新生儿肺透明膜病患儿50例，对照其临床治疗过程中的X线片与CT影像学资料，观察分析诊断结果。结果新生儿肺透明膜病的典型病症包括胸片表现的细颗粒状、网格状、支气管充气征以及两肺野透亮度减低等．并发症包括肺出血、肺炎和气胸等。分析表明，肺部病变检出率CT扫描与X线片二者比较差异有高度统计学意义（P〈0．01）；并发症检出率CT扫描与X线片二者比较差异有统计学意义（P〈0．05）。结论X线片与CT对新生儿肺透明膜病的诊断是相互补充的，对临床高度可疑但X线片观察不能排除的患儿，应及时实施CT扫描．这对该疾病的鉴别诊断以及发现并发症等具有重要的指导性意义。

Objective To compare and analyse the results of the neonatal hyaline membrane disease X-ray films and CT diagnosis and explore its applications. Methods 50 cases hyaline membrane disease children from November 2009 to November 2011 in our hospital was selected, its clinical treatment in the process of X-ray film and CT imaging data was analysised, to the results of the diagnosis were observed and analyzed. Results Neonatal hyaline membrane disease typical symptoms, including chest X-ray performance of fine granular grid, air bronchogram, and two lung fields through the brightness to reduce and so on. The complications include pulmonary hemorrhage, pneumonia and pneumothorax. The analysis showed that the lung lesion detection rate of CT scan and X-ray film contrast the two was statistically significant （P 〈 0.01）. Contrasted CT scan and X-ray film detection rate of complications, and the difference was statistically significant （P 〈 0.05）. Conclusion X-ray films and CT complement each other hyaline membrane disease diagnosis, highly suspicious of clinical X-ray film observation can not be ruled out in children, the differential diagnosis of the disease and the discovery of complications has important guiding significance.
