Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen is an right sided indwelling catheter with tip at SVC / RA junction an NG tube , with tip and side - port curled in the expected location of the gastric fundus . There are low inspiratory volumes , similar to 1 day earlier . Triangular opacity at the left base medially , with new obscuration of the medial left hemidiaphragm , could reflect some superimposed atelectasis . Otherwise , I doubt significant interval change . Again seen is vascular plethora , likely accentuated by low lung volumes and patchy atelectasis at the right lung base . The cardiomediastinal silhouette is not well delineated due to low inspiratory volumes . Prominence of the right hilar region probably reflects part of the cardiomediastinal silhouette , accentuated by low lung volumes and differences in rotation . No pneumothorax detected .
    OUTPUT:
    
1 . Persistent low lung volumes with bibasilar atelectasis . New triangular opacity at the left base medially may reflect some superimposed segmental atelectasis . If clinically indicated , a lateral view may help for further assessment . 2 . No pneumothorax detected . 3 . Mild vascular plethora is similar to the prior film and likely accentuated by low lung volumes . No gross effusions .
