Purpose This clinical trial evaluates the diagnostic accuracy, clinical utility, and follow-up efficacy of chest X-ray (CXR) versus computed tomography (CT) in pediatric pneumonia. The study enrolled 200 children presenting with clinical symptoms of pneumonia. Imaging outcomes were analyzed to compare sensitivity, specificity, radiation exposure, and impact on management. The findings underscore the role of CXR as the primary diagnostic tool while highlighting the adjunctive utility of CT in complex cases.
Read more Methods and materials IntroductionPneumonia is a leading cause of morbidity and mortality in children worldwide. While chest X-ray remains the first-line imaging modality due to its availability and low radiation dose, CT offers superior anatomical detail. This study aims to compare the diagnostic and follow-up capabilities of CXR and CT in pediatric pneumonia.MethodsStudy Design A prospective, randomized clinical trial conducted over 24 months at a tertiary pediatric hospital. Participants: 200 children (ages 1 month to 12 years) with clinically suspected pneumonia were included. Groups: Participants were...
Read more Results ResultsDemographics Mean age: 4.5 years (range: 1 month to 12 years). Gender distribution: 52% male, 48% female. Diagnostic Accuracy Sensitivity: CXR 72%, CT 96%. Specificity: CXR 88%, CT 92%. CT identified subtle ground-glass opacities and small abscesses that were missed on CXR in 20% of cases. Imaging Findings CXR: Detected consolidation in 80 cases, pleural effusion in 15 cases, but was less effective for interstitial changes and small effusions. CT: Detected early interstitial changes, ground-glass opacities, and abscesses in 30% of cases, guiding early intervention in severe presentations. Radiation Exposure Mean...
Read more Conclusion DiscussionStrengths of CXR CXR is cost-effective, readily available, and exposes patients to minimal radiation, making it ideal for initial diagnosis and follow-up in uncomplicated cases. Its diagnostic performance is robust for typical bacterial pneumonia, characterized by consolidation and pleural effusion. Limitations of CXR Limited sensitivity for detecting subtle or atypical findings, including viral pneumonia and early abscess formation. Overlap in radiographic features can make differentiation between viral and bacterial pneumonia challenging. Strengths of CT CT offers unparalleled sensitivity for detecting subtle parenchymal changes, interstitial patterns, and complications...
