Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size remains mildly enlarged . Aortic knob is densely calcified . The mediastinal contour is unchanged . Right hilar opacity is similar to the previous examinations . Rounded opacity projecting over the right mid lung field likely reflects fluid loculated within the major fissure . A moderate right pleural effusion and trace left pleural effusion are noted , and there is mild pulmonary edema . Patchy opacity in the lung bases may reflect atelectasis but infection or aspiration is not excluded . No pneumothorax is present . Emphysematous changes are again seen in the lungs .
    OUTPUT:
    
1 . Mild pulmonary edema and moderate size right and small left pleural effusions . Small amount of fluid is loculated within the right major fissure . 2 . Patchy opacity in the lung bases may reflect atelectasis but infection or aspiration can not be excluded . 3 . Unchanged chronic right hilar opacity .
