【摘要】 目的提高对新生儿呼吸窘迫综合征(NRDS)计算机X线摄影(CR)影像表现的认识,增强诊断和鉴别诊断能力。方法采用高分辨率影像板对临床疑诊病例进行床边摄片,并选择经临床确诊、治疗且有完整CR影像资料的NRDS患儿共50例,动态观察其CR改变及临床特点。结果并吸入性肺炎9例,感染性肺炎8例,肺出血3例,气胸2例。影像表现共分4级,Ⅰ级5例,Ⅱ级20例,Ⅲ级22例,Ⅳ级3例。典型CR征象为肺野透过度降低,肺内广泛的网状、颗粒状密度增高影,并伴多发的含气支气管像。结论CR床边摄影是临床诊断NRDS最重要的影像方法,应结合临床不断提高对NRDS的诊断、鉴别诊断能力。更多还原

【Abstract】 Objective To improve the knowledge and diagnostic ability of imagiology on neonatal respiratory distress syndrome (NRDS) computed radiograph(CR).Methods The doubtful patients were done to photographs bedside using the high resolution imaging plate, 50 cases of newborn with NRDS were selected whose clinical diagnosed clearly and had been treated and had the complete CR image documents.The CR change and clinical characteristics were observed dynamically.Results Nine of 50 cases were combined with aspirated pneumonia,8 cases with infective pneumonia,3 cases with intra-alveolar hemorrage,and 2 cases with pneumothorax.Accoding to X-ray manifestations,all cases were divided into four stages:Ⅰ stage(n=5), Ⅱ stage(n=20),Ⅲ stage(n=22),Ⅳstage(n=3).Typical CR signs included:the pulmonary lucency decreasd,wide-ranging net and grain shadowes of high density, and in companing with a lot of air brunchus sing.Conclusions Computed radiography is the most important imaging method in diagnosis of NRDS bedside ,and shall be improved the ability of diagnosis and differential of NRDS combined with the clinic.更多还原
