Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest demonstrate that the lungs are slightly hyperinflated and there is bibasilar scarring , but otherwise they are clear of focal opacities concerning for pneumonia . Surgical clip is noted in the right upper lobe , perhaps from a prior surgical resection . There is no evidence of pulmonary edema . The mediastinum is normal in its size . Once again , there is lucency under the left hemidiaphragm which persists on the lateral view and is most likely due to a portion of colon . Although , if the patient 's clinical exam dictates , a left lateral decubitus film would be helpful to definitively rule out free air . Minimal wedging of the mid thoracic vertebral bodies and a kyphosis is also noted .
    OUTPUT:
    
1 . No evidence of acute cardiopulmonary process . 2 . Elevation of the left hemidiaphragm with lucency underneath is most likely due to a portion of colon .
