Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube tip 5 .6 cm above the carina . NG tube extends beneath the diaphragm , off film , again seen looping in the stomach . Right central line tip overlies mid / distal SVC . Right IJ Swan - Ganz catheter tip again overlies the main pulmonary artery . Left - sided battery pack again noted . There is a lead extending cephalad . Note is made that is difficult to trace the lead on the available images . The cardiomediastinal silhouette is unchanged . Again seen is patchy retrocardiac opacity and minimal patchy opacity in the right cardiophrenic region , similar to prior . No gross effusion . Doubt CHF .
    OUTPUT:
    
Lines and tubes as described . Battery pack with lead extending cephalad beyond the upper edge of this film . While this may be due to technical factors , note is made that is difficult to trace the lead between the battery pack and the third posterior rib on the current radiograph . Clinical correlation is requested . Patchy opacities at both bases , unchanged .
