    INPUT: In comparison to the most recent prior , a left internal jugular central venous catheter has been placed . The catheter terminates in the mid SVC . Again noted are low lung volumes . No new focal consolidation is identified . There is no pneumothorax . Again seen is a possible diffusion on the right , unchanged since the prior examination . The cardiac silhouette is borderline enlarged and the pulmonary vascularity is indistinct , which may be suggestive of mild edema .
    OUTPUT:
    
Left internal jugular venous catheter terminates at the mid SVC . Otherwise no significant interval change .
