Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with the prior study an endotracheal tube has been placed which terminates 4 .5 cm from the carina , directed slightly at the right tracheal wall . An enteric tube courses below the diaphragm and terminates within the duodenum . Extensive parenchymal abnormality including chronic interstitial process with superimposed parenchymal opacities likely representing pneumonia is grossly unchanged from the recent prior study . There is no pneumothorax , or right - sided pleural effusion . A probable small left pleural effusion is similar to the prior study . There is also probably a superimposed interstitial pulmonary edema . A left pectoral pacemaker and its 3 leads project in unchanged location .
    OUTPUT:
    
1 . Interval intubation and placement of an enteric tube , which appear well positioned . 2 . Unchanged extensive chronic interstitial abnormality with superimposed airspace opacities likely representing pneumonia . There is also probably superimposed mild interstitial edema
