The nasogastric tube ends in the body of the stomach with side holes at or just below the level of the gastroesophageal junction , needs to be further advanced for optimal positioning . The NG tube has been retracted since earlier study . New heterogeneous opacification in the right lung base , is worrisome for either developing pneumonia or aspiration . A small right pleural effusion is likely present . The left lung is clear , without effusion or pneumothorax .
    OUTPUT:
    
1 . Heterogeneous new opacification in the right lung base , worrisome for either a developing pneumonia or aspiration . 2 . NG tube has been retracted since prior study , with sideholes at or just below the gastroesophageal junction , needs to be advanced further for optimal positioning .
