Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube terminates approximately 7 cm above the carina . Enteric tube is seen coursing to the lower hemithorax near the midline , with the tip out of view of this film . Mild cardiomegaly is overall stable compared to the prior exam . Low lung volumes appears to exaggerate the perihilar vascular structures , however aside from mild tortuosity of the thoracic aorta , the hilar and mediastinal contours are unremarkable . Along the right heart border in the mid right lung , there is a focal opacity , which appears new compared to the prior exam . Small bilateral pleural effusions are new . Note is made of mild bibasilar atelectasis , left greater than right , with obscuration of the left hemidiaphragm . There is no evidence of a pneumothorax .
    OUTPUT:
    
1 . Focal opacity along the right heart border in the mid right lung , pneumonia vs aspiration vs atelectasis . 2 . Interval worsening of mild bibasilar atelectasis , left greater than right , with obscuration of the left hemidiaphragm , left retrocardiac consolidation not excluded .
