Results
Demographics
- 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 radiation dose: CXR 0.02 mSv; CT 1.5 mSv (low-dose protocol).
- CT’s higher radiation dose raised concerns, especially in cases requiring multiple follow-up scans.
Clinical Impact
- CXR: Guided initial management in 82% of cases with no significant complications.
- CT: Modified management in 40% of cases, including adjustments in antibiotic therapy and decisions for surgical drainage of abscesses or empyema.
Follow-Up Findings
- CXR was sufficient for routine monitoring in 85% of cases.
- CT was required in 15% for unresolved symptoms, identifying complications such as abscess formation or bronchiectasis.
