    INPUT: The left subclavian line tip overlies the right - sided mediastinal portion , at the level of the carina and compatible with the SVC . Cardiomediastinal contours are unchanged . Symmetrical , bilateral central parenchymal opacities are noted as before , consistent with pulmonary congestion and demonstrate interval improvement . Hazy densities at the bases of the lungs persist suggesting continued presence of bilateral pleural effusions in this semi-erect patient . There is no pneumothorax .
    OUTPUT:
    
1 . Left subclavian line tip overlies right - sided mediastinal portion , at level of the carina and compatible with the SVC without evidence of pneumothorax . 2 . Interval improvement of pulmonary congestion with continued presence of bilateral pleural effusions .
