Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Diffuse bilateral opacities are improved . There is better aeration of the left lung . However , there is increased opacification of the right base . Prominence of the right hilum continues to be seen . ET tube is elevated in the trachea and recommend advancement . Gastric tube ends in the stomach and outside the view of the radiograph . Right central venous line ends in the lower SVC .
    OUTPUT:
    
1 . Improved aeration of the left lung . 2 . Mild improvement of the right lung opacity ; however , there is increasing opacity of the right base . This may represent redistribution of pulmonary edema , acute respiratory distress syndrome , or atelectasis and / or focal edema superimposed on background pneumonia , noting that many opacities appear asymmetric , focal and fairly unchanging . 3 . ET tube is approximately 9 cm above the carina . Recommend advancement . 4 . Persistent bilateral hilar enlargement , although particularly prominent on the right ; this is probably due to pulmonary congestion , lymphadenpathy or enlargement of pulmonary arteries , and a combination of these factors . However , other etiologies such as a mass are not excluded , and if this appearance were to fail to resolve to baseline following acute illness , then chest CT might be appropriate in follow - up .
