Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is moderately enlarged . The aorta is mildly calcified and tortuous . The central pulmonary vessels are engorged and hazy , accompanied by patchy interstitial opacities , most dense at the left base . An ET tube terminates 4 .7 cm above the carina . An orogastric tube terminates within the stomach . There is no pneumothorax or large effusion .
    OUTPUT:
    
1 . Extensive bilateral patchy pulmonary opacities . In the setting of central vascular congestion , this is most likely severe pulmonary edema , but pneumonia can not be excluded , particularly at the left base . 2 . ET tube terminating 4 .7 cm above the carina . Orogastric tube within the stomach .
