Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal image of the chest demonstrates an increase in right perihilar vascular opacity , likely reflecting an increase in vascular congestion or possibly a perihilar consolidation . There is no pneumothorax or pleural effusion . There appears to be some interval obscuring of the left hemidiaphragm , which could be consistent with a retrocardiac atelectasis versus consolidation . This would be better visualized on a lateral image . The cardiomediastinal silhouette appears grossly unchanged , although portions of the heart border are less clearly visualized on this exam due to adjacent opacities . There has been interval placement of an NG tube , which is seen with the tip at least in the proximal stomach , though whether it continues to pass beyond this point is not clearly seen on this image . A followup abdominal x-ray to verify the location and the tip of the NG tube is recommended .
    OUTPUT:
    
Interval worsening of right perihilar opacity that could be consistent with worsening vascular congestion or consolidation . Possible development of a left lung base retrocardiac opacity , which could represent atelectasis or possibly consolidation .
