    INPUT: Mild cardiomegaly is re- demonstrated . The aorta remains mildly tortuous with atherosclerotic calcifications seen at the arch . No pulmonary edema is present . A small right pleural effusion which is partially loculated in the minor fissure appears decreased in size compared to the previous radiograph . Trace left pleural effusion also has decreased from the prior radiograph . Patchy opacity in the right lung base likely reflects compressive atelectasis and appears improved . No new focal consolidation or pneumothorax is present . No acute osseous abnormalities detected .
    OUTPUT:
    
1 . Small right pleural effusion , partially loculated in the minor fissure , decreased from the previous chest radiograph . Improving right basilar compressive atelectasis . 2 . Decreased size of trace left pleural effusion .
