Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Multiple lines and tubes are similar to the prior film . Allowing for changes in the patient position , the left mediastinal border is better defined , but no definite change in the cardio mediastinal silhouette is identified . Renewed visualization of left hemidiaphragm suggests an element of clearing at the left lung base . Slight interval clearing of opacity in the upper zones may also have occurred . Nonetheless , again seen is diffuse opacity in both lungs , compatible with pulmonary edema . No gross effusion is identified . Residual consolidation in the left lower lobe is indicated by air bronchograms projecting over the retrocardiac region . No gross effusions identified . No pneumothorax detected .
    OUTPUT:
    
Pulmonary edema , with interval improvement of opacities predominantly at the left base and , to a lesser extent , in the upper zones . The possibility of an associated infectious infiltrate would be difficult to exclude .
