“…12,16,17 It is difficult to compare our findings with the other studies because they analyzed older patients who had BPD, and used different statistical analyses. Although the contexts differed, the reliability was substantial or moderate for the majority of the abnormalities seen on CT.…”

“…For the other CT findings, the kappa ranged from fair/moderate to moderate/substantial. 17 In the situations where we found the paradox between a high proportion of observed agreement and low kappa, other indices need to be analyzed in order to identify the sources of disagreement. Our study showed a high proportion of observed agreement and poor kappa coefficient values in relation to two types of abnormalities seen on CT: air trapping (kappa; 0.34) and interlobular septal thickening (kappa: 0.06).…”

“…12 Ochiai et al analyzed HRCT scans performed on premature newborns who were diagnosed with BPD. 17 All of the tests were performed on patients with a similar age range to those in our study. To determine the interobserver reliability of the CT findings, they used kappa statistics and Spearman's rank-sum test.…”

“…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.…”

CONTEXT AND OBJECTIVE: High-resolution computed tomography (HRCT) of the lungs is more sensitive than radiographs for evaluating pulmonary disease, but little has been described about HRCT interpretation during the neonatal period or shortly afterwards. The aim here was to evaluate the reliability of the interpretation of HRCT among very low birth weight premature infants (VLBWPI; < 1500 g). DESIGN AND SETTING: Cross-sectional study on intra and interobserver reliability of HRCT on VLBWPI. METHODS: 86 VLBWPI underwent HRCT. Two pediatric radiologists analyzed the HRCT images. The reliability was measured by the proportion of agreement, kappa coefficient (KC) and positive and negative agreement indices. RESULTS: For radiologist A, the intraobserver reliability KC was 0.79 (confidence interval, CI: 0.54-1.00) for normal/abnormal examinations; for each abnormality on CT, KC ranged from 0.05 to 1.00. For radiologist B, the intraobserver reliability KC was 0.79 (CI: 0.54-1.00) for normal/abnormal examinations; for each abnormality on CT, KC ranged from 0.37 to 0.83. The interobserver agreement was 88% for normal/abnormal examinations and KC was 0.71 (CI: 0.5- 0.93); for most abnormal findings, KC ranged from 0.51-0.67. CONCLUSION: For normal/abnormal examinations, the intra and interobserver agreements were substantial. For most of the imaging findings, the intraobserver agreement ranged from moderate to substantial. Our data demonstrate that in clinical practice, there is no reason for more than one tomographic image evaluator, provided that this person is well trained in VLBWPI HRCT interpretation. Analysis by different observers should be reserved for research and for difficult cases in clinical contexts.

ВВЕДЕНИЕПрофилактические стратегии на этапах формирова-ния и течения бронхолегочной дисплазии (БЛД) привели к существенному изменению патоморфоза заболева-ния на современном этапе. Внедрение новых методов интенсивной терапии и принципов выхаживания недо-ношенных детей с экстремально низкой (ЭНМТ) и очень низкой массой тела (ОНМТ) при рождении, в т. ч. профи-лактического и лечебного использования препаратов сурфактанта, способствовало появлению значительного
