Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 4 .6 cm from the carina . An enteric tube is noted within the distal esophagus , though the tip is not well visualized . Lung volumes are low . Heart size is mildly enlarged . The aorta is tortuous . Crowding of bronchovascular structures is present with mild pulmonary vascular congestion . Bibasilar airspace opacities may reflect areas of atelectasis . Numerous clips are seen in the right neck . No acute osseous abnormalities detected .
    OUTPUT:
    
1 . Standard positioning of the endotracheal tube . 2 . Enteric tube courses into the distal esophagus , however the tip is not well visualized on this exam . Dedicated radiographs of the upper abdomen are recommended to better assess the location of the tip of the enteric tube . 3 . Low lung volumes with bibasilar patchy opacities , likely atelectasis . Infection or aspiration is not excluded in the correct clinical setting . 4 . Probable mild pulmonary vascular congestion .
