Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A new left basilar chest tube is demonstrated with interval decrease in size of the left pleural effusion , now moderate in extent . There is a persistent layering pleural effusion on the right which is moderate in size . Patchy bibasilar airspace opacities likely reflect atelectasis though infection can not be excluded . Cardiac , mediastinal and hilar contours are unchanged . No definite pneumothorax is present . Nasogastric tube tip terminates at the distal esophagus , and should be advanced for optimal positioning .
    OUTPUT:
    
1 . Interval decrease in size of the left pleural effusion , now moderate in extent with left basilar chest tube in place . No pneumothorax . 2 . Persistent moderate right pleural effusion . Bibasilar patchy opacities likely reflect atelectasis , but infection is not excluded . 3 . Nasogastric tube tip is suboptimally position , terminating within the distal esophagus , and should be advanced .
