Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube terminates 7 cm above the carina . A left - sided PICC terminates in the upper SVC . The heart is within normal limits for size on this AP view . The pulmonary vasculature is engorged without overt pulmonary edema . There is free air under the right hemidiaphragm . Blunting of the costophrenic angles likely reflects small bilateral pleural effusions . Increased bibasilar opacities may reflect atelectasis or infection .
    OUTPUT:
    
Free air underneath the right hemidiaphragm may be related to recent abdominal surgery , however if there is concern for viscus perforation recommend CT . Small bilateral effusions and bibasilar opacities likely reflect atelectasis however infection aspiration should be considered .
