Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . The cardiac , mediastinal and hilar contours are probably unchanged allowing for the limitations of technique . There is no pleural effusion or pneumothorax . There are patchy opacities at both lung bases that are poorly delineated , but early pneumonia , atelectasis or even areas of slight aspiration are possible . This is all seen in the background of a mild interstitial abnormality suggesting fluid overload .
    OUTPUT:
    
Findings suggesting mild vascular congestion , although technique is limited . Patchy basilar opacities , non-specific . Repeat radiographs may be helpful in short - term follow - up to re-assess ; preferably , this could be done with standard PA and lateral technique if feasible clinically .
