Overview
Imaging with chest x-rays remains the gold standard of diagnosis when supported with other lab findings but it is recommended that, apart from x-ray findings, the entire clinical picture be taken into consideration before treatment is started. Patterns commonly found on imaging include lobar or focal nonsegmental pneumonia, lobular or multifocal bronchopneumonia, and diffuse or interstitial (atypical) pneumonia. Radiological findings may take 6-12 weeks to clear.
