Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac and mediastinal silhouettes appear stable compared to the prior examination . Again seen at the right costophrenic angle is some haziness which when corresponding to the prior radiograph and CT examination likely represents a prominence of mediastinal fat and post resection changes . Adjacent changes are seen involving diminutive right lateral ribs which appear chronic . Linear scarring or atelectasis is seen at the left base , similar or perhaps slightly worse than on the prior study . No new consolidative process .
    OUTPUT:
    
Left retrocardiac atelectasis , similar or slightly worse than prior . No definite consolidative process . Overall very similar appearance of the chest when compared to the radiograph from ___ . It is notable that the right upper lobe changes described on the prior CT from ___ were not particularly apparent on the radiograph on the preceding day , and therefore slight worsening of this process might not be evident on these radiographs .
