Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a left IJ central venous catheter which terminates at the cavoatrial junction . Lung volumes are low . Prominence of the cardiomediastinal silhouettes likely relates to low lung volumes and AP technique . The hila are unremarkable . Mild prominence of the interstitium diffusely likely relates to crowding of normal bronchovascular structures . There is bibasilar atelectasis . There is no focal lung consolidation . There is no evidence of pulmonary vascular congestion . It is difficult to exclude trace bilateral pleural effusions . There is no pneumothorax .
    OUTPUT:
    
Left IJ center venous catheter terminating at the level of the cavoatrial junction . No pneumothorax . Low lung volumes .
