Reliability of the chest radiograph in the diagnosis of lower respiratory infections in young children.

摘要: Objective This study was conducted to determine the reliability of detecting features and making diagnoses lower respiratory infections from chest radiograms in young infants. Methods Forty infants younger than 6 months age admitted with tract infection a tertiary care pediatric hospital were independently reviewed on two separate occasions by three radiologists blinded patients' clinical diagnoses. For each radiograph noted whether feature present, absent or equivocal standardized form. The examined hyperinflation, peribronchial thickening, perihilar linear opacities, atelectasis consolidation. On same form radiologist indicated normal showed airways and/or airspace disease. Within between observer agreement calculated average weighted kappa statistic. Results for radiologic wall consolidation 0.85, 0.76, 0.87, 0.86 0.91, respectively. results these 0.83, 0.55, 0.82, 0.78 0.79, within statistics interpretation radiographic best disease (within, 0.92; between, 0.91), 0.80; 0.66) radiogram 0.68; 0.48). presence highly correlated diagnosis all radiologists. Conclusions Clinicians basing should be aware that there is variation intraobserver interobserver among used diagnosis. There also how specific are interpreting radiogram. However, cardinal finding pneumonia appears reliable.
