    INPUT: PA and lateral radiographs of the chest demonstrate interval resolution of pulmonary edema from the mid and upper lung field when compared to the study from three days ago . There are persistent bilateral lower lung opacities representing residual edema and / or atelectasis . Small pleural effusions are also present . The hilar and cardiomediastinal contours are normal . There is no pneumothorax . There is no evidence of residual pneumomediastinum . A right subclavian hemodialysis catheter has been placed and terminates at the expected location of the cavoatrial junction .
    OUTPUT:
    
1 . Interval improvement in pulmonary edema with some persistence in the bilateral lung bases . 2 . Small bilateral pleural effusions and atelectasis . 3 . No evidence of pneumomediastinum .
