    INPUT: AP and lateral images of the chest . The lung volumes are low with crowding of the vasulature and no overt pulmonary edema . Bibisilar opacities are seen which likely represent atelectasis , but can not exclude pneumonia or aspiration in the correct clinical setting . There are small bilateral pleural effusions . Cardiomediastinal contours are difficult to assess given low volumes and patient marked rotation but likely stable . No pneumothorax .
    OUTPUT:
    
Bibasilar opacities favoring atelectasis in the setting of low lung volumes . Hoever , pneumonia or aspiration can not be exluded .
