摘要
目的探讨新生儿肺透明膜病(HMD)的直接数字化X线摄影(DR)表现,以期提高其早期诊治水平。方法收集资料完整的HMD患儿35例,对其临床及DR表现进行综合分析。结果根据DR征象可分为四个阶段,分别为全肺野呈毛玻璃改变,无支气管充气征;全肺野满布网状粟粒状阴影,出现支气管充气征;以上两个阶段病征更明显,同时有小片状肺实变和局部肺萎陷阴影,心影模糊隐约可见;大片或整叶肺实变和萎陷,呈普遍均匀,致密白色的完全不透明阴影,谓之"白色肺",心影轮廓消失,横膈向上移位或模糊,而支气管充气征仍然可见。结论DR是诊断HMD最重要的影像检查方法。
Objective To investigate the performance of direct digital radiography in neonatal pulmonary hyaline membrane disease. Methods 35 cases with HMD who had complete materials were studied clinically and radiologically. Results According to the manifestations of DR all cases were divided into four stages, namely, ground glass for the whole lung field with no air bronchus sign; whole lung field covered with net and grain shadows with air bronchus sign; more obvious symptoms of the above two stages, with small pieces lung consolidation and partial lung collapse shadow hearts shadow looming on the horizon blurred; large leaf or whole lung consolidation and collapse, showed generally uniform, dense white completely opaque shadows, named as ＂white lung＂, with heart shadow contours disappearing, diaphragm upward shift or fuzzy, while the air bronchus sign still visible. Conclusions DR is the most important imaging method in diagnosis of HMD.
