Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The left internal jugular central venous catheter tip terminates in the mid SVC . No pneumothorax is identified . The remaining lines and tubes remain in standard positions . Cardiac and mediastinal contours are similar . There is continued diffuse interstitial and alveolar opacities , perhaps minimally improved in the interval , compatible with mild pulmonary edema . More focal opacities within the right mid lung field and right lung base again could reflect areas of coexistent infection . Hazy opacity in the right lung base likely reflects the presence of a small layering pleural effusion , as seen previously .
    OUTPUT:
    
Left internal jugular central venous catheter tip terminates in the mid SVC . No pneumothorax . Slight interval improvement in mild pulmonary edema with more focal opacities in the right lung suggestive of coexistent multifocal pneumonia . Small right pleural effusion , probably unchanged .
