Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette is upper limits of normal in size and is accompanied by pulmonary vascular congestion , peribronchial cuffing and diffuse interstitial opacities . Lung volumes appear relatively increased , suggesting the possibility of COPD . Small pleural effusions are present bilaterally . Bones are diffusely demineralized , and spinal hardware is present in the imaged portion of the upper lumbar spine , incompletely evaluated on this radiograph .
    OUTPUT:
    
1 . Diffuse bilateral interstitial opacities are most likely due to interstitial edema in the setting of history of pulmonary edema on recent outside chest radiograph ( unavailable ) . Followup radiographs may be helpful after diuresis to confirm resolution and to exclude other causes of interstitial lung disease . 2 . Small bilateral pleural effusions .
