Abstract

Introduction: Computed tomography is considered as the diagnostic gold standard for following up the majority of pediatric chest X-ray opacities; however, radiation, cost, and waiting times has lead to the efforts to seek for diagnostic alternatives. This study was conducted to determine the diagnostic accuracy of the ultrasound (US) in detecting the causes of pediatric CXR opacities. 

Methods: This study was conducted on the pediatric patients with CXR opacity referring to Dr. Sheikh Hospital in Mashhad, Iran during 2016 - 2017. After undergoing ultrasound exam, the patients were followed to obtain the final diagnosis based on reference standard (RF). The accuracy of the US was  calculated in detection of thoracic lesions. P value <0.05 was considered to be significance level. 


Results: The most common diagnostic cause of CXR opacity based on RF was pneumonia (n=46, 35-38%), thymus (n=37, 28-46%), bone and soft tissue mass (n=12, 9.23%), cystic lesions (n=11, 8.46%), and diaphragmatic lesions (n=10, 7.69%), as well as intrathoracic masses and empyema (n=7, 5.38%). In only 4 patients (3.07%), the final diagnosis based on RF was inconsistent with the US diagnosis. The diagnostic accuracy of the US was 100% in the diagnosis of bone and soft tissue masses, diaphragmatic lesions, empyema and normal thymus, also 96.92% for pneumonia, and 99.23% for cystic lesions and intrathoracic masses. 


Conclusion:
Regarding to the assessed diagnostic accuracy, it appears that the US can be a reliable diagnostic tool for detecting the main cause of pediatric CXR opacity.
