支气管肺发育不良影像学特征分析

Analysis of imaging features of bronchopulmonary dysplasia

支气管肺发育不良(BPD)是以肺泡和肺微血管发育不良为特征的慢性呼吸系统疾病,见于早产儿,是造成早产儿死亡和长期并发症的重要原因。胸部影像学检查是该病的主要诊断依据,不仅能显示典型的影像征象:肺过度充气、肺纤维化与肺不张,同时可作为评估病情严重程度和进展的主要依据,对指导BPD患儿临床治疗和改善预后具有重要意义。

Bronchopulmonary dysplasia(BPD)is a chronic respiratory disease characterized by alveolar and pulmonary microvascular dysplasia.It happens in premature infants,which is a major cause of death and long-term complications in premature infants.Chest radiology examination is essential for BPD,which not only reveals main radiological features such as pulmonary hyperinflation,pulmonary fibrosis and atelectasis,but also evaluates the severity and progression.These provide significant information for clinical treatment and follow-up study of children with BPD.
