Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are linear opacities in the left lower lobe which is not as extensive as the area of collapse seen on recent CT , but likely represents a small residual atelectasis . There is also a linear opacity projecting over the heart on the lateral view , which likely corresponds to atelectasis in the right middle lobe . The lungs are otherwise clear without focal consolidation , pleural effusion or pneumothorax . The pulmonary vasculature is not engorged . The cardiac silhouette size is borderline but unchanged . The mediastinal and hilar contours are within normal limits . The thoracic aorta is tortuous .
    OUTPUT:
    
Small residual atelectasis in the left lower lobe decreased from that seen on recent CT . Minimal right middle lobe atelectasis . No focal consolidation .
