Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is prominence of the pulmonary interstitium with increased opacity in both lower lobes . This likely represents mild pulmonary edema with asymmetric involvement of the lower lobes ; however aspiration or aspiration pneumonia can not be excluded . The heart is mildly enlarged . There are small bilateral pleural effusions . No pneumothorax present . The visualized upper abdomen is unremarkable .
    OUTPUT:
    
1 . Cardiomegaly with interstitial edema . More confluent bibasilar opacities could reflect dependent distribution of edema or a coexisting process such as aspiration or infectious pneumonia . Short - term followup radiographs after diuresis may be helpful in this regard . 2 . Small bilateral pleural effusions .
