    INPUT: Portable AP chest radiograph . Diffuse interstitial and parenchymal opacities are decreased slightly compatible with minimal improvement in edema , particularly with reduction of the density of the right base . However upper to mid right lung more confluent opacity is decreased but still notable focally and may reflect asymmetric edema or masked infectious process . Cardiac enlargement is mild and stable . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Slight improvement in mild to moderate pulmonary edema . Slightly more confluent mid right lung opacity could reflect infectious process the appropriate setting versus asymmetry of edema . Attention after continued diuresis .
