Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is poor inspiratory effort and low lung volumes . Linear opacities within the bilateral lung bases likely reflect subsegmental atelectasis . No confluent consolidation is identified . There is no interstitial edema or pleural effusions . Mediastinal and hilar contours appear within normal limits . The cardiac silhouette is likely exaggerated due to the AP technique .
    OUTPUT:
    
Low lung volumes with probable subsegmental atelectasis . Atelectasis can be a feature of acute pulmonary embolism and should be considered clinically .
