Chest computed tomography findings in bronchopulmonary dysplasia and correlation with lung function

Abstract

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.

Intra and interobserver reliability of the interpretation of high-resolution computed tomography on the lungs of premature infants

“…At the time when these scans were performed, the CT equipment did not allow changes to the technical settings, to adjust the time taken and thus the radiation dose applied to the lowest possible amounts under the circumstances. Therefore, the settings used were higher than those proposed by Lucaya et al in 2000 (35 to 60 mA/s), 24 but similar to those used recently by Mahut et al 16 with equipment equivalent to ours. The latter authors performed HRCT with settings of 100 mA and 1.0 s, on premature infants born between January 1999 and March 2001, all of which displayed criteria for BPD.…”

“…23 It used more radiation than the dose recommended by Lucaya et al in 2000 24 because the equipment on which the examinations were performed did not allow changes to the technical parameters. Mahut et al 16 recently presented the results from CT scans on premature infants born between 1999 and 2001 that were performed using a similar scanner (ProSpeed Advantage™) and similar parameters to those used in our study (100 mA and a scan duration of 1.0s).…”

“…Studies have demonstrated that high-resolution computed tomography (HRCT) is more sensitive than radiographs for evaluating lung disease, 9,10 but little has been described in the literature on HRCT in relation to the neonatal period or shortly afterwards, or in relation to the consistency of its interpretation. [11][12][13][14][15][16][17] Studies on the reliability of chest radiographs on patients with chronic lung disease have shown wide variation in the interpretation of images by radiologists. [18][19][20] Bloomfield et al showed poor interobserver agreement for pulmonary parenchymal abnormalities on chest x-rays of premature infants in neonatal intensive care units.…”

Bronchopulmonary Dysplasia in Post-Surfactant Era: Results of an Objective Assessment of the Disease

“…Метод рассматривают как основу рентгенодиагностики заболевания, даже несмо-тря на его недостаточную информативность [10,11].…”

“…«Золотым стандартом» в обследовании пациентов с БЛД является компьютерная томография (КТ) орга -нов грудной полости с высоким разрешением [10,11]. Этот метод позволяет хорошо визуализировать струк-турные изменения легочной ткани, не обнаруживае-мые на рентгенограмме, а также определять харак тер и объем поражения дыхательных путей, в т. ч. общую гиперинфляцию, фокусы снижения пневмати за ции и лентообразных уплотнений, степень поражения бронхов и бронхиол, локализацию эмфи зема тозных участков, изменения в малом круге кровообраще -ния [11,12].…”
