Abstract:
PURPOSE: To evalute high resolution CT(HRCT) findings in infants with bronchopulmonary dysplasia(BPD). MATERIALS AND METHODS: In 13 infants(age range, 1-12 months ; 11 premature babies, two full-term babies ; birthweight, 0.97-3.88kg ; mean 2,03kg) with clinico-radiologically suggested BPD, HRCT findings of the lung were reviewed retrospectively. Spiral CT using ultra high bone algorithm, 1mm collimation with 5-8mm interval, and 0.7sec scan time was perfomed without regard to breathing-control of infants. Three radiologists each analysed the HRCT findings twice. RESULTS: HRCT findings of BPD were as follows : parenchymal bands(n=13), interlobular septal thickenings(n=12), multifocal hyperaeration involving lobar or segmental distribution(n=7), and involving lobular distribution or small cyst-like lesion(n=4), centrilobular nodules(n=7), consolidation and/or atelectasis(n=7), and bronchovascular bundle thickening(n=6). CONCLUSION: Parenchymal bands, interlobular septal thickenings, and multifocal hyperaerations were the major findings in cases of bronchopulmonary dysplasia whereas, centrilobular nodules, consolidation and/or atelectasis, and bronchovascular bundle thickenings were the minor findings. These findings may be used as basic data in the evaluation of BPD in future studies.
