    INPUT: Dilated loops of large bowel are noted in the abdomen . Intraluminal air is likely accounting for the lucency abutting the hemidiaphragms bilaterally . However , pneumoperitoneum is difficult to completely exclude on the basis of this exam . The cardiomediastinal and hilar contours are normal . The lungs are hypoinflated with bibasilar atelectasis . There is no pneumothorax or large pleural effusion . There is no focal consolidation concerning for pneumonia .
    OUTPUT:
    
1 . Dilated loops of small and large bowel in the imaged portion of the abdomen , likely accounting for increased lucency abutting the hemidiaphragms . If clinical concern persists for pneumoperitoneum , upright abdominal radiographs or CT is recommended for further evaluation . 2 . Low lung volumes with bibasilar atelectasis .
