Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right internal jugular catheter terminates in the upper SVC . Endotracheal tube terminates 1 .2 cm above the carina . Recommend withdrawal of the endotracheal tube by several cm for more optimal positioning . Nasogastric tube extends into the stomach . The median sternotomy wires are intact . There is stable , mild cardiomegaly . Mediastinal and hilar contours are unchanged . Interval improvement in bibasilar opacities . Apparent increased opacity projecting over the right apex is likely secondary to superimposed external structures . Recommend more symmetric positioning with removal of external structures on subsequent radiographs . No pneumothorax . Interval improvement in mild pulmonary edema .
    OUTPUT:
    
1 . Interval improvement in mild pulmonary edema and bibasilar opacities . 2 . Endotracheal tube terminates 1 .2 cm above the carina . Recommend withdrawal by several cm for more optimal positioning .
