Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a right internal jugular central venous catheter with tip in the mid SVC . No large pneumothorax is identified on this supine exam . Endotracheal tube and enteric tubes are in unchanged positions . Worsening pulmonary opacities in the perihilar regions and upper lung fields bilaterally may reflect a combination of worsening mild pulmonary edema and atelectasis . Heart size remains mildly enlarged . Superior mediastinal widening may be due to low lung volumes and supine AP positioning . Catheter terminating in the region of the T1 vertebral body again is unchanged , possibly a temperature probe , with cervical spinal hardware partially imaged .
    OUTPUT:
    
Right internal jugular central venous catheter tip in the mid SVC . No large pneumothorax . Worsening perihilar and upper lobe airspace opacities which may reflect a combination of worsening mild pulmonary edema and increased atelectasis . Infection is not excluded .
