Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is an ET tube which terminates 8 mm above the carina . This could be safely retracted 2 cm for proper positioning in the trachea . There is no OG tube seen . There is a widened appearance to the mediastinum , most prominently in the right paratracheal region . The differential includes lymphadenopathy , large mass , or hemorrhage emanating from a mediastinal great vessel . There are low lung volumes . There is retrocardiac opacification and obscuring of the left hemidiaphragm likely due to left lower lobe atelectasis . There is right basilar platelike atelectasis . There are no pneumothoraces or effusions seen .
    OUTPUT:
    
1 . Widened mediastinum . Differential includes lymphadenopathy , large mass , or hemorrhage emanating from a mediastinal great vessel . 2 . ET tube terminating 8 mm above the carina . This may be safely retracted 2 cm for repositioning in distal trachea . 3 . Bibasilar atelectasis .
