Abstract

Standard chest radiographs have been shown to be insensitive for the diagnosis of morphologic abnormalities of airways. Computed tomography is the most sensitive and specific investigation to diagnose emphysema. However, as emphysema may be missed on computed tomography, this investigation cannot be used to definitely rule out the diagnosis. Computed tomography may contribute to the investigation of bronchiolitis, and it is now considered as the gold standard for establishing the diagnosis of bronchiectasis. Imaging may contribute to identify complications such as bronchopulmonary infection, pulmonary hypertension, pneumothorax, cancer of the lung, compressive bullae, and pulmonary embolism.

Chest radiography in children aged 2-59 months diagnosed with non-severe pneumonia as defined by World Health Organization: descriptive multicentre study in Pakistan.

OBJECTIVES: To evaluate the chest radiographs of children diagnosed with non-severe pneumonia on the basis of the current World Health Organization guidelines (fast breathing alone) for radiological evidence of pneumonia. DESIGN: Descriptive analysis. SETTING: Outpatient departments of six hospitals in four cities in Pakistan. PARTICIPANTS: 2000 children with non-severe pneumonia were enrolled; 1932 children were selected for chest radiography. INTERVENTIONS: Two consultant radiologists used standardised WHO definitions to evaluate chest radiographs; no clinical information was made available to them. If they disagreed, the radiographs were read by a third radiologist; the final classification was based on agreement between two of the three radiologists. MAIN OUTCOME MEASURES: Presence or absence of pneumonia on radiographs. RESULTS: Chest radiographs were reported normal in 1519 children (82%). Radiological evidence of pneumonia was reported in only 263 (14%) children, most of whom had interstitial pneumonitis. Lobar consolidation was present in only 26 children. The duration of illness did not correlate significantly with the presence of radiological changes (relative risk 1.17, 95% confidence interval 0.91 to 1.49). CONCLUSION: Most children diagnosed with non-severe pneumonia on the basis of the current WHO definition had normal chest radiographs.
