Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal , and hilar contours appear unchanged . There are streaky new posterior basilar opacities , probably in the right lower lobe and suggestive of minor atelectasis , but otherwise the lungs appear clear aside from scattered unchanged small calcified granulomas . The bony structures are unremarkable .
    OUTPUT:
    
Streaky new posterior right lower lobe opacities . Although an infectious process is difficult to completely exclude , the appearance would be compatible with atelectasis . Correlation with clinical findings is suggested . If symptoms were to persist , then follow - up radiographs might be appropriate .
