    INPUT: Low bilateral lung volumes . No focal consolidation or pneumothorax identified . The trace bilateral pleural effusions are better assessed on the earlier CT of the chest . Since the prior radiograph the tip of the left PICC line has been retracted , now projecting over the upper SVC with the tip folded back on itself and likely extending into the azygos vein . A feeding tube extends below the level of the diaphragms but beyond the field of view of this radiograph .
    OUTPUT:
    
No focal consolidation . Low bilateral lung volumes . Since the prior radiograph there has been interval retraction of the left PICC line as described above .
