Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Dense irregular opacity within the right upper lobe is re - demonstrated with somewhat improved aeration compared to the prior study from ___ . The quantity of opacity which reflects scar versus active infection is somewhat difficult to determine . No additional opacities are seen with near complete clearing of the left lung opacities . Trace right pleural effusion is noted . The cardiomediastinal contour is unremarkable aside from upward traction of the right hilum . Left PICC terminates in the distal SVC . Feeding tube terminates in the upper stomach . Of note , the weighted dense tip is not identified on the current examination . It is uncertain if it is fractured or if the tube was unchanged to one without a weighted tip .
    OUTPUT:
    
1 . Irregular right upper lung opacity with intervally improved peripheral aeration . It is difficult to assess how much of this is scarring versus active infection , though in total there is interval improvement from the prior study . Trace to small right effusion is also improved . Near complete resolution of left lung opacities . 2 . Nasogastric tube does not project with the weighted tip as was seen on the prior study . Correlate with history of changed tube to determine whether tube is fractured .
