This study aimed to (1) describe CT findings in infants with BPD and (2) correlate the CT findings with lung function abnormalities.Study design and method: Retrospective review of 41 very low birthweight infants with BPD, who were referred for pulmonary investigations at between 10 and 20 months after birth because of persistent respiratory symptoms, and underwent CT and lung function tests.Results: None of the infants had normal CT findings. The most frequent abnormalities were hyperlucent areas (n = 36; 88%), linear opacities (n = 39; 95%), and triangular subpleural opacities (n = 26; 63%). Bronchiectasis was not seen. None of the CT abnormalities correlated with the maximum expiratory flow at functional residual capacity (VmaxFRC). In contrast, increased number of subpleural opacities and limited linear opacities were associated with low FRC and longer duration of neonatal oxygen exposure. The numbers of triangular subpleural opacities also correlated with duration of mechanical ventilation.Conclusions: Despite advances in neonatal care, many CT findings in infants with BPD are similar to those observed in the pre-surfactant era, and are still associated with duration of supplemental oxygen and mechanical ventilation. The absence of bronchial involvement in the present study was the most striking difference from previous studies.
