Chest X-ray Interpretation

Both intra-rater and inter-rater agreement among human CXR readers is poor. CAPTURE radiological assessment evaluates specific features including consolidation, pleural effusion, intrathoracic lymphadenopathy, cavitation, and miliary infiltrates. Every CXR in the CAPTURE repository receives a consensus radiological classification from at least two expert readers who are blinded to all clinical and microbiological information. Current CAD products cannot interpret lateral CXR views, so lateral images in the CAPTURE repository are stored separately for potential future use. Chest radiographs are a key diagnostic tool for paediatric TB, but their optimal interpretation requires specialist radiologists who are largely absent in high-burden settings.
