87例新生儿肺炎胸片与CT图像对比分析

Analysis of Neonatal Pneumonia X-ray and CT Features

目的总结新生儿肺炎X线与CT平片特征,提高X线胸片对该病影像学的确诊率。方法对安阳市妇幼保健院87例资料完整的新生儿肺炎的临床、平片及CT资料进行回顾性分析。结果87例肺炎中平片表现为肺门增宽、肺纹理增粗等支气管炎表现的31例,表现为斑点状及斑片状阴影等肺炎表现的56例、其中并发肺实变的6例。平片与临床新生儿肺炎的符合率为64.4%;而CT表现为肺纹理增多、增粗等支气管炎表现的12例,表现为斑点状及斑片状高密度影等肺炎表现的75例、其中并发肺实变的28例,CT与临床诊断符合率为86.2%,差异具有统计学意义。结论X线胸片肺炎的正确诊断率较低,CT扫描是胸部摄片的重要补充手段。

Objective To summarize the neonatal pneumonia X-ray and CT features, enhance the image of the disease rate of correct diagnosis. Methods 87 cases of neonatal pneumonia complete information on clinic, plain film and CT data were retrospectively analyzed. Results In 87 cases of pneumonia, 37 cases showed hilar widened, lung markings thickening performance, 56 cases showed punctate and patchy shadow. Complicated atelectasis as seen in 6 cases. Plain film and clinical neonatal pneumonia in line were with the rate of 64.4% ; 12 cases＇ CT showed hilar widened, lung markings thickening performance, 75 cases showed mottling and patchy high-density. Complicated atelectasis was seen in 28 cases, CT and clinical diagnosis of pneumonia in line with the rate of 86.2%. By X^2 test （P 〈 0.05） , there was significant difference. Conclusion X-ray of the correct diagnosis of neonatal pneumonia is relatively low, CT scans of the neonatal pneumonia are an important supplement.
