Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a right - sided internal jugular central venous catheter with tip projecting over the right atrium . No evidence of pneumothorax is seen . Redemonstration of vague opacity within the right upper lung is again noted and is more apparent on this exam . The technique is somewhat different ; this film is somewhat more blurry . Vague opacity is also seen at the right lung base , probably atelectasis . Probable small bilateral pleural effusions are noted . Heart size is unchanged . There is no evidence of pneumoperitoneum and osseous structures are unchanged .
    OUTPUT:
    
1 . Interval placement of right - sided central venous catheter with tip projecting over the right atrium without evidence of pneumothorax . 2 . More conspicuous opacity in the right upper lobe , a possible developing infectious process but potentially the apparent increase is due to differences in technique .
