The pneumonia severity index was used as a level of confidence. Present study, chest CT was considered as a reference standard and The objective of the present study was to compareĭiagnostic parameters of lung ultrasound with chest X-ray inĬhildren with suspected pneumonia, in a Chinese setting. Suggested to be insensitive and has relatively low accuracy The chest X-ray is typically requestedīy pediatricians in children with suspected pneumonia ( 12), however, this method has been Typically used in routine clinical practice or included as aĭiagnostic method for pneumonia in children ( 11). Operator-dependent and requires skilled sonographers ( 10), therefore, ultrasonography is not Lung ultrasound is a promisingĪdjunctive technique in patients with community-acquired pneumonia,īy which radiation can be avoided ( 8) and secondary technical parameters (forĮxample, a thinner chest wall) can be successfully evaluated Subpleural lung consolidation in adults with pneumonia ( 7). However, MRI is rarely the preferredĬhoice for the evaluation of pulmonary parenchyma due to theĭecreased likelihood of having proton content in the lungs, as wellĪs possible respiratory and cardiac pulsation artifacts ( 5). Tissues and the provision of high soft-tissue contrast ( 5). The lack of ionizing radiation, the ability to better characterize Resonance imaging (MRI) has several advantages over CT, including Of lung diseases, except for pleural effusions ( 3), but has a high risk of radiation Indeed, CT is the only imaging technique that can assess the wholeĭisplays the highest sensitivity and specificity for the majority User-friendly, but also allows the characterization of the lung Provides a three-dimensional view, which not only makes it Lateral view chest X-ray, to decrease radiological exposure With suspected pneumonia, the diagnosis is confirmed by a single Pneumonia is a leading cause of disease among In conclusion, lung ultrasound is a non‑invasive and simple method that could be used for the diagnosis of suspected pneumonia in children. For a pneumonia severity index of <3, the chest CT displayed a good beneficial score, followed by the lung ultrasound and chest radiograph. Compared with the chest CT, the lung ultrasound displayed 0.906 sensitivity and 0.661 accuracy, while the chest radiograph displayed 0.793 sensitivity and 0.559 accuracy. The chest CT successfully detected a liquefied area, enhancement and necrosis of the lungs. The lung ultrasound successfully detected pleural effusion and perilesional inflammatory edema. The chest radiograph successfully detected subpleural lung consolidation and dense lung opacity. Beneficial score analysis for each diagnostic modality was evaluated according to the pneumonia severity index. Data regarding the chest radiograph, lung ultrasound and chest CT were collected and analyzed. Medical records of 949 children, aged ≤16 years, with suspected pneumonia were reviewed. The objective of the present study was to compare diagnostic parameters of lung ultrasound with chest X‑ray in children with suspected pneumonia, using CT as a reference standard. Lung ultrasonography can identify subpleural lung consolidation in adults, but it is not accepted in routine clinical practice and is also not used for the diagnosis of children with pneumonia. Computed tomography (CT) allows for the characterization of the consolidation in pneumonia but has a high risk of radiation exposure in children. The chest X‑ray is routinely requested by pediatricians for children with suspected pneumonia, but has been demonstrated to be an insensitive method with relatively low accuracy.
