    INPUT: Cardiomediastinal contours are normal . Lungs and pleural surfaces are clear . Mild elevation of left hemidiaphragm is probably related to adjacent distension of the stomach and splenic flexure . Lucency below the left hemidiaphragm is likely related to air within the stomach .
    OUTPUT:
    
1 . No radiographic evidence of congestive heart failure or pneumonia . 2 . Lucency below left hemidiaphragm is likely due to air within a distended stomach . If there is clinical suspicion for free intraperitoneal air , standard lateral chest radiograph or left lateral decubitus abdominal view would be recommended .
