Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the prior radiograph , the amount of subcutaneous emphysema has slightly decreased . Post - surgical changes are seen at the right base adjacent to the pericardial surface . There is no definite pneumothorax , although a small pneumothorax can not be excluded as it would be obscured by the subcutaneous air . The right lung has increased hazy opacification in comparison to the prior exam , which is most likely technical due to the degree of penetration . Less likely , it could be a new large pleural effusion , but given that it is not present on the lateral exam , it is likely technical . Moderate cardiomegaly is unchanged . There has been slight increase in the left basilar atelectasis .
    OUTPUT:
