Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is at the upper limits of normal size . The mediastinal and hilar contours are otherwise unremarkable . There are streaky right infrahilar opacities in the right lower lobe , but more suggestive of atelectasis than pneumonia . Likewise , there is also suspected minor atelectasis in the right middle lobe . The lungs appear otherwise clear without suspicious findings . There is no pleural effusion or pneumothorax . The lungs appear mildly hyperinflated . Bony structures are unremarkable .
    OUTPUT:
    
No radiographic findings suspicious for malignancy ; however chest CT is much more sensitive for malignancy if there is substantial clinical concern .
