To evaluate the reproducibility of the Ultrafast CT (UFCT) scoring system and assess its usefulness in monitoring clinical severity in infants with bronchopulmonary dysplasia (BPD).
UFCT scoring was done in 22 infants (15 boys and 7 girls aged 1 to 37 months) with BPD. A total of 258 lung fields were evaluated for the presence of hyperaeration, linear opacities, triangular subpleural opacities, and bronchovascular bundle distortion or thickening, and UFCT scores were given. Intraobserver and interobserver agreement and reproducibility of UFCT scores were statistically analyzed. In 12 patients, UFCT scores were linearly correlated with clinical severity scores based on respiratory dysfunction and complexity of care.
"Hyperaeration," which was the most frequent (18 of 22, 81.8%) finding, showed high concordance (kappa = 0.73, p < 0.001, kappa = 0.59, p < 0.001), and its UFCT scores significantly correlated with intraobserver and interobserver analyses (r = 0.94, p < 0.001, r = 0.82, p < 0.001, respectively). UFCT scores for hyperaeration significantly correlated with clinical scores (r = 0.75, p < 0.01), whereas those for the others did not.
UFCT is useful for assessing BPD. Hyperaeration was the most common and reproducible finding, and its extent significantly correlated with clinical severity.
评估超快速CT（UFCT）评分系统的可重复性，并评估其在监测支气管肺发育不良（BPD）婴儿临床严重程度方面的实用性。
对22例患有BPD的婴儿（15例男孩和7例女孩，年龄1至37个月）进行UFCT评分。共评估258个肺野，观察有无肺过度充气、线状阴影、三角形胸膜下阴影以及支气管血管束扭曲或增粗情况，并给出UFCT评分。对观察者内和观察者间的一致性以及UFCT评分的可重复性进行统计学分析。在12例患者中，UFCT评分与基于呼吸功能障碍和护理复杂性的临床严重程度评分呈线性相关。
“肺过度充气”是最常见的表现（22例中有18例，81.8%），显示出高度一致性（kappa = 0.73，p < 0.001，kappa = 0.59，p < 0.001），其UFCT评分与观察者内和观察者间分析显著相关（分别为r = 0.94，p < 0.001，r = 0.82，p < 0.001）。肺过度充气的UFCT评分与临床评分显著相关（r = 0.75，p < 0.01），而其他表现的评分则无相关性。
UFCT对评估BPD有用。肺过度充气是最常见且可重复的表现，其程度与临床严重程度显著相关。
