    INPUT: Right pigtail pleural catheter is in unchanged position . Lung volume is lower than before , possibly due to less suboptimal inspiration during image acquisition . There is persistent right lung opacity and moderate loculated pleural effusion . Small left lung base opacity and pleural effusion is noted . Enlarged cardiac silhouette is similar to before .
    OUTPUT:
    
Bilateral lung aeration is decreased than before , which may be due to differences in inspiration between the studies . There is persistent right lung opacity and moderate pleural effusion as well as small left lung base opacity and small left pleural effusion .
