AI Summary & Key Takeaways
AI InsightThe diagnostic accuracy of the US was 100% in the diagnosis of bone and soft tissue masses, diaphragmatic lesions, empyema, andnormal thymus, and the accuracy was 96.92% for pneumonia, and 99.23% for cystic lesions and intrathoracic masses.CONCLUSION: Regarding the assessed diagnostic accuracy, the US can be a reliable diagnostic tool to differentiate the main cause ofpediatric CXR opacity.

OBJECTIVES: Computed tomography is considered as the diagnostic gold standard for following up the majority of pediatric chest X-ray(CXR) opacities. However, radiation, cost, and waiting times have led to search for diagnostic alternatives. This study was conducted todetermine the diagnostic accuracy of the ultrasound (US) in detecting the causes of pediatric CXR opacities.MATERIALS AND METHODS: This study was conducted on the pediatric patients with CXR opacity referring to Dr. Sheikh Hospitalin Mashhad, Iran during 2016-2017. After undergoing the US exam, the patients were followed to obtain the final diagnosis based onreference standard (RF). The accuracy of the US was calculated in detection of thoracic lesions. P value <0.05 was considered to besignificant.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 intrathoracicmasses and empyema (n=7, 5.38%). In only four 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, andnormal thymus, and the accuracy was 96.92% for pneumonia, and 99.23% for cystic lesions and intrathoracic masses.CONCLUSION: Regarding the assessed diagnostic accuracy, the US can be a reliable diagnostic tool to differentiate the main cause ofpediatric CXR opacity.
