    INPUT: Lung volumes are decreased compared to the prior exam . This results in accentuation of the cardiac silhouette size which is likely borderline enlarged . The aorta is mildly unfolded . Pulmonary vascularity is normal . Minimal left basilar streaky opacity likely reflects atelectasis . There is no focal consolidation , pleural effusion or pneumothorax is seen . No acute osseous abnormalities are present .
    OUTPUT:
    
Low lung volumes with left basilar streaky opacity most likely reflective of atelectasis .
