Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Tracheostomy tube and right PICC remain in unchanged positions . Heart size is mildly enlarged . The mediastinal and hilar contours are unchanged . Persistent bibasilar airspace opacities may reflect atelectasis , although infection is difficult to exclude . Small left pleural effusion is relatively unchanged . Previously noted right pleural effusion appears improved . There is no pneumothorax . No pulmonary vascular congestion is noted . Cholecystectomy clips are noted in the right upper quadrant of the abdomen . Percutaneous GJ tube is partially imaged in the upper abdomen .
    OUTPUT:
    
Bibasilar airspace opacities persist , likely atelectasis though infection is difficult to exclude . Persistent small left pleural effusion , and interval decrease in size of the right pleural effusion which is likely miniscule .
