Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided Port - A - Cath tip terminates within the SVC / right atrial junction . Heart size is normal . The mediastinal and hilar contours are unchanged . Pulmonary vasculature is not engorged . Lungs are hyperinflated with mild emphysematous changes again noted in the lung apices . Trace bilateral pleural effusions appear improved compared to the previous examinations . Streaky opacities in the lung bases may reflect atelectasis , but infection can not be excluded in the correct clinical setting . Known pulmonary nodules seen on prior chest CT are not well assessed on the current radiograph . No pneumothorax is identified . No acute osseous abnormality is detected . Mild degenerative changes are seen in the thoracic spine .
    OUTPUT:
    
Trace bilateral pleural effusions , likely improved from prior exams . Streaky opacities within the lung bases may reflect atelectasis but infection can not be excluded in the correct clinical setting .
