Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable semi-upright chest radiograph shows stable positioning of supporting lines and tubes . Note is again made that the left - sided central venous catheter tip is directed towards the right lateral wall of the SVC and could be advanced 2 cm or pulled back 1 cm . Diffuse haziness in the parenchyma , particularly in the perihilar regions where peribronchial cuffing is seen , suggests edema , though ARDS could give a similar picture . Marked cardiomegaly and atherosclerotic plaque in the thoracic aorta are unchanged .
    OUTPUT:
    
No significant radiographic improvement in edema or ARDS and cardiomegaly . If left - sided central venous catheter tip is to be longstanding , recommend either withdrawal 1 cm or advancement of approximately 2 cm to avoid tip abutting right lateral wall of SVC .
