Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with the prior film , the chest tube is been removed . No pneumothorax is detected . No gross effusion is identified . Otherwise , I doubt significant interval change . Extensive opacities in both lungs are again seen . The differential diagnosis includes CHF with interstitial alveolar edema , but the possibility of associated pneumonic infiltrates can not be entirely excluded .
    OUTPUT:
    
Interval removal of right chest tube . No pneumothorax detected . Extensive bilateral opacities remain present . Please see comment above .
