OBJECTIVES: The diagnosis of pediatric @entity497 ( @entity497 ) is based on clinical criteria. Even though chest x- @entity16039 (CXR) is only recommended in severe cases, it is often requested from physicians in mild cases, thus increasing radiation exposure. @entity358 ( @entity358 ) is not included in the diagnostic workup. The objective of this study was to evaluate the diagnostic performance of @entity358 against CXR. METHODS: @entity1 who presented to the emergency department with clinical signs suggesting @entity497 and had already been evaluated with a CXR were included in the study. Availability of a pediatric sonographer expert in @entity358 was also considered a criterion for participation. Chest x- @entity16039 and @entity358 were considered positive for @entity497 in cases of alveolar or interstitial pattern of disease. The diagnostic criterion standard was the ex post diagnosis of @entity55 , made by an independent senior expert pediatrician, after evaluation of the complete medical chart. RESULTS: Sixty-nine @entity1 were enrolled in the study, with 66 of 69 positive for @entity497 . Receiver operating characteristic curve analysis results for CXR were 95.5% sensitivity and 100% specificity, whereas for @entity358 , sensitivity was reported 92.42% and specificity 100%. Comparison of the 2 receiver operating characteristic curves revealed no difference in the diagnostic value of the 2 methods for the diagnosis of @entity55 (P = 0.658). However, @entity358 classified more cases as @entity66 compared with CXR. CONCLUSIONS: @entity358 plays a significant role in the detection of @entity497 , not inferior to CXR. The aim of this study was to encourage the use of ultrasound as a first-line examination for @entity497 in @entity1 .
