Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post coronary artery bypass graft surgery . There is a persistent loculated pleural effusion along the minor fissure on the right , but decreased even since the recent chest CT , comparing to scout views from that study . A loculated basilar and lateral pleural effusion , however , is probably not substantially changed since the recent prior CT , with corresponding atelectasis . It is not possible to exclude a persistent small left - sided pleural effusion that may be obscured , but none is clearly visible . The left base appears similar to the prior scout view . The chest is hyperinflated . The bones are probably demineralized . There is similar slight rightward convex curvature centered along the lower thoracic spine .
    OUTPUT:
    
Decrease in loculated pleural effusion along the right major fissure with no other definite change . No definite evidence of superimposed acute process .
