Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single semi-upright portable view of the chest was obtained . The left internal jugular central venous catheter is seen terminating at the SVC / brachiocephalic junction . If this is the same catheter that was present on ___ , it is more proximal in position as compared to the prior study . No evidence of pneumothorax is seen . There are low lung volumes . Obscuration of the diaphragms may be due to small pleural effusions and / or atelectasis . There is prominence of the pulmonary vasculature suggesting mild pulmonary edema . The cardiac and mediastinal silhouettes are grossly stable .
    OUTPUT:
    
Left internal jugular central venous catheter terminates at the SVC / brachiocephalic junction without evidence of pneumothorax . Low lung volumes . Obscuration of the diaphragms may be due to small pleural effusions with overlying atelectasis . Enlargement and indistinctness of the hila and increased perihilar opacities , while may be accentuated by low lung volumes , also suggest component of mild edema .
