Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . The cardiac silhouette size remains mild to moderately enlarged . The mediastinal contour is stable . There is crowding of the bronchovascular structures without overt pulmonary edema . Patchy opacities in the lung bases may reflect areas of atelectasis . No large pleural effusion or pneumothorax is identified .
    OUTPUT:
    
Low lung volumes . Bibasilar patchy opacities may reflect areas of atelectasis though consider followup PA and lateral views of the chest with improved inspiratory effort for better assessment of this region .
