Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a nasogastric tube which terminates at the level of the GE junction on the initial radiograph . On the followup radiograph , the tube was advanced to at least the level of the duodenal bulb . A right PICC line is unchanged in position , terminating in the low SVC . There is no pneumothorax . Unchanged obscuration of the medial left hemidiaphragm may be due to atelectasis or previous aspiration . However , there are increased airspace and interstitial right perihilar opacities with new bronchial wall thickening , which may reflect developing aspiration pneumonia . An old healed left clavicular fracture is noted .
    OUTPUT:
    
NG tube terminates at the level of the proximal duodenum . New right perihilar opacity may reflect developing aspiration pneumonia . Stable retrocardiac airspace opacity , which may reflect previous aspiration or atelectasis .
