    INPUT: Endotracheal tube tip terminates 4 .4 cm from the carina . An enteric tube is noted which courses below the left hemidiaphragm , into the stomach and off the inferior borders of the film . Heart size is normal . The aortic knob is calcified . Mediastinal and hilar contours are unremarkable . Streaky opacity in the left lower lobe likely reflects atelectasis . No focal consolidation or pneumothorax is seen . Minimal blunting of the right costophrenic sulcus may suggest a trace pleural effusion . No acute osseous abnormality is identified .
    OUTPUT:
    
1 . Endotracheal and enteric tubes are in standard positions . 2 . Left basilar patchy opacity , likely atelectasis . 3 . Probable trace right pleural effusion .
