Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in supine position . The patient is intubated , the ETT terminating in the trachea 5 cm above the level of the carina . No pneumothorax is identified . An NG tube reaches well below the diaphragm . Heart size is difficult to assess as patient is in supine position , but gross cardiac enlargement can not be identified . Aorta is poorly identified on this portable chest examination . There is marked pulmonary congestive pattern with bilateral extensive densities in practically all lung areas . As the periphery is relatively free , the present finding is most likely representing acute pulmonary edema . Possibility of superimposed scattered aspirations can not be excluded . Remarkable is the absence of any pleural effusion on the lung bases as the lateral pleural sinuses are free . Our records include only an old portable chest examination dated ___ . The lungs were clear at that time , and no gross abnormality was seen .
    OUTPUT:
    
ETT and NG tube in correct positions . No pneumothorax . Bilateral advanced pulmonary parenchymal infiltrates , most likely representing edema . Patient underwent CT examination with angiography at the same date .
