Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . There is opacification along the base of each hemithorax suggesting moderate - sized pleural effusions with parenchymal opacities , most commonly due to atelectasis . The cardiac contours are partly obscured , but the heart is probably at least mildly enlarged . There is no evidence for parenchymal edema . Mild degenerative changes affect lower thoracic levels . The thoracic spine curves to the left side to a mild - to - moderate degree .
    OUTPUT:
    
Bilateral pleural effusions with opacities that can probably be attributed to atelectasis , although not entirely specific , as well as suspected mild cardiomegaly ; however , no parenchymal edema identified .
