Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable AP supine radiograph demonstrates interval placement of an endotracheal tube , its tip which projects within the right bronchial mainstem . Retraction approximately 3 cm is advised for more appropriate positioning . An enteric tube descends the thorax in uncomplicated course , it s tip out of the field of view . There is no pneumothorax . Interval placement of right internal jugular central venous catheter is noted , it s tip in the mid SVC . Opacification in the retrocardiac region may reflect aspiration new relative to prior study . There is no large pleural effusion . Cardiomediastinal and hilar contours are stable . No evidence of pulmonary edema .
    OUTPUT:
    
1 . Endotracheal tube low in position within the right mainstem bronchus for which repositioning and retraction 3 cm is advised . 2 . Interval placement of right internal jugular central venous catheter without evidence of pneumothorax though technique is suboptimal in the detection of pneumothorax . 3 . Retrocardiac opacity is new relative to prior study , likely aspiration .
