Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 3 cm from the carina . An enteric tube is noted coursing below the left hemidiaphragm , off the inferior borders of the film . The heart size is normal . The aorta is slightly unfolded . There are low lung volumes with crowding of the bronchovascular structures and mild pulmonary vascular congestion . More focal opacity within the retrocardiac region could reflect an area of atelectasis , but infection or aspiration are also possible . No pleural effusion or pneumothorax is seen . No acute osseous abnormalities demonstrated .
    OUTPUT:
    
1 . Standard position of the endotracheal tube . Enteric tube tip courses below the left hemidiaphragm off the inferior borders of the film . 2 . Mild pulmonary vascular congestion . 3 . More focal patchy opacity in the left lung base could reflect an area of atelectasis , but infection or aspiration are not excluded .
