Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right PIC line terminates at the cavoatrial junction . ETT terminates approximately 5 .4 cm above the carina . Orogastric tube terminates in the proximal stomach with side holes approximately at the gastroesophageal junction and should be advanced approximately 5 cm to be an optimal position . Lung volumes are low and exaggerate heart size , which is likely mildly enlarged . Previously seen minimal bibasilar atelectasis has improved . There is no focal consolidation , effusion or pneumothorax . There is minimal central vascular congestion without overt pulmonary edema . Note is made of calcified gallstones .
    OUTPUT:
    
1 . Right PICC line terminates at the cavoatrial junction . ETT terminates approximately 5 .4 cm above the carina . Orogastric tube terminates in the proximal stomach and should be advanced approximately 5 cm to ensure that the side ports are beyond the GE junction . 2 . Improved minimal bibasilar atelectasis . 3 . Minimal central vascular congestion without overt pulmonary edema . Stable mild cardiomegaly . 4 . Cholelithiasis .
