Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable AP view of the chest . ET tube terminates in the mid - to - lower thoracic trachea , approximately 3 .2 cm from the carina . The film was obtained in a lordotic position making evaluation somewhat difficult and the carina is not well visualized . An enteric tube courses through the esophagus to the stomach with the tip beyond the inferior border of the film . There is significant opacity of the right upper lobe with some residual areas of aeration or cystic change . There are coarse interstitial markings bilaterally and reticular opacity in the right costophrenic sulcus likely representing atelectasis or prior scarring ; however , aspiration can not be excluded . The heart is not enlarged . There is no frank pulmonary edema . There is no large pleural effusion or pneumothorax .
    OUTPUT:
    
1 . ET tube approximately 3 .2 cm from the carina . 2 . Right upper lobe opacity possibly infection or aspiration . Underlying mass is possible given history . See subsequent CT for additional details .
