摘　　要：目的:探讨新生儿湿肺症的CT征像特点,提高对该病的诊断正确率。方法:回顾性分析近5年来经临床诊断新生儿湿肺症15例的CT资料,测量其肺平均密度值。结果:新生儿湿肺症的CT影像特点主要有:双肺血管影增粗、模糊,伴小片状稍高密度灶,肺平均密度值-500～-400Hu(轻度,8例));肺野呈磨砂玻璃样改变的云雾状稍高密度灶,肺平均密度值-399～-300Hu(中度,5例;)全肺完全变白而呈“白肺”;肺平均密度值大于-300Hu(重度,2例)。结论:新生儿湿肺的CT表现有一定特点,可为临床诊断提供重要影像学依据,同时评估疗效和预后有一定意义。Objective: To study CT findings of wet lung disease of neonatal and to analyze pathogenesis so as to improve our understanding.Methods: The clinical manifestations and CT findings of 15 wet lung disease of neonatal collected from 1998 to 2003 were analyzed retrospectively.The mean lung density was measured on CT images.Results: characteristic CT findings of wet lung disease of neonatal were : mildly(8 cases): roughening and blurring of the shadow of pulmonary blood vessels with small parenclyma.The mean lung density range from -500 to -400 Hu;moderately(5 cases):slight high density with ground-glass like cloudy shadow.The mean lung density range from -399u to -300 Hu;severely(2cases): high density foci on the whole lungs almost like “white lung”.The mean lung density > -300 Hu.Conclusion: the CT manifestation of wet lung disease of neonatal has some features that can provide image evidences,but also are available for the assessment of treatment effects.
