Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Flattening of diaphragms and widening of the AP diameter of the thorax is compatible with underlying COPD . Lung volumes are slightly decreased compared to the previous radiograph . Small bilateral pleural effusions have increased since the prior study , and there worsening patchy bibasilar airspace opacities which could reflect atelectasis but infection is not excluded . Heart size also appears mildly enlarged with mild pulmonary vascular congestion , both of which have increased since the prior radiograph . Chain sutures are noted in the left mid lung . There is no pneumothorax . No acute osseous abnormalities detected .
    OUTPUT:
    
Patchy bibasilar airspace opacities may reflect atelectasis but infection or aspiration can not be excluded . Increased small bilateral pleural effusions . Mild cardiomegaly and mild pulmonary vascular congestion , increased from prior .
