Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in semi-erect position . Analysis is performed in direct comparison with the next preceding similar study obtained eight hours earlier during the same day . Positions of previously described ETT and right internal jugular approach central venous line are unchanged . No pneumothorax has developed . The previously identified extensive pulmonary infiltrates in the left hemithorax remain . They have been located on previous CT ( ___ ) to involve almost exclusively the left upper lobe and extending into the lingula . These abnormalities persist and have not undergone any major interval change since the next preceding examination . As has been reviewed on previous examinations , pulmonary vasculature never showed any conclusive evidence for marked venous congestion , and there is no evidence for pulmonary congestive edema . On this latest portable image , one can identify a small stent resembling metallic structure , approximately 7 mm wide and 12 mm long , overlying the area of the left main bronchus . It is unclear from the chest film if this relates to any intrabronchial intervention . An NG tube reaches well below the diaphragm and terminates in the moderately gas - distended stomach .
    OUTPUT:
    
No radiographic evidence of cardiogenic pulmonary edema .
