Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is persistent opacification of the left hemithorax with leftward mediastinal shift suggesting collapse of the left lower lobe . A large left pleural effusion is unchanged . Compared with the immediate prior study of ___ at 22 :23 , there is slightly improved aeration of the left mainstem bronchus as well as slightly increased air in the left lung field . However , the partially visualized left - sided airways appear abnormal , suggesting widespread bronchiectasis . The pulmonary edema in the right lung appears slightly improved , but there abnormal opacities throughout the right lung , suggesting underlying chronic pulmonary disease . If no cross-sectional imaging has been performed to date ( none is available for review at this time ) , CT is recommended for further evaluation of any underlying parenchymal process . The endotracheal tube and enteric tube are in unchanged standard position . There are multilevel age indeterminate vertebral compression fractures of the visualized thoracic spine .
    OUTPUT:
    
1 . Persistent opacification of the left hemithorax with leftward mediastinal shift suggesting left lower lobe collapse . 2 . Slightly improved aeration of the left mainstem bronchus . 3 . Bronchiectatic left - sided airways , and an abnormal right lung field , for which a chest CT is recommended if outside studies are not available for review .
