Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided central line is present , tip over distal SVC . No pneumothorax is detected . There are low inspiratory volumes , with bibasilar atelectasis . This is less pronounced than on ___ . The cardiac silhouette is probably unchanged . Prominence of the right hilum is similar to the prior study , with some patchy opacity in the right infrahilar region . There is minimal upper zone redistribution , without overt CHF . The appearance is improved compared with the prior study . Again noted is a normal variant incomplete azygos fissure . The possibility of hazy density in the fissure can not be entirely excluded , but I suspect this is an artifact due to overlying soft tissues . No gross effusion .
    OUTPUT:
    
Minimal bibasilar atelectasis , including in the right infrahilar region . The appearance is less pronounced than on ___ . No definite consolidation , though an early infiltrate would be difficult to exclude in this setting .
