目的建立一种新的胸部CT评分系统，用于评估支气管肺发育不良（BPD）患者的临床状况，并与改良的Edwards X线评分系统进行比较。三位放射科医师将CT结果分为三类--过度膨胀、肺气肿或纤维/间质异常--并开发了一种新的评分系统。我们评估了观察者间的可重复性，并调查了这种分类系统是否反映了这些patients.Results的BPD的严重程度的CT评分有可接受的可重复性（相关系数[ee] = 0.721至0.839）。具有更严重形式的BPD的亚组具有更高的CT评分。CT评分与经后36周临床评分（cc = 0.367）和氧疗时间（cc = 0.537）相关。结论新的胸部CT评分系统对BPD患者出院前的临床状态评估和预后预测具有更高的客观性和准确性。
Objective To develop a new scoring system for computed tomography (CT) of the chest for assessing the clinical status of patients with bronchopulmonary dysplasia (BPD) in comparison with a modified Edwards roentgenographic scoring system.Study design Preterm infants diagnosed with BPD (n = 42) were assessed prospectively by chest CT scan at the time of discharge. Three radiologists classified the CT findings into I of 3 categories-hyperexpansion, emphysema, or fibrous/interstitial abnormalities-and developed a new scoring system. We assessed interobserver reproducibility and investigated whether this classification system reflected the severity of BPD in these patients.Results The CT scores had acceptable reproducibility (coefficient of correlation [ee] = 0.721 to 0.839). The subgroup with a more severe form of BPD had a higher CT score. The CT score correlated with the clinical score at 36 weeks of postmenstrual age (cc = 0.367) and the duration of oxygen therapy (cc = 0.537). Patients who were discharged home on oxygen had higher CT scores than patients who were not.Conclusions The new chest CT scoring system may have higher objectivity and accuracy in terms of predischarge assessment of clinical status as well as prediction of the prognosis of patients with BPD.
