Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube ends 3 .7 cm above carina . The feeding tube is in adequate position below the diaphragm . Left - sided PICC line is in mid SVC . Bilateral moderate pleural effusion with bibasilar atelectasis is unchanged . Right upper lobe decreased opacity could reflect improvement of the lung process versus modification in ventilation parameters . Pulmonary edema is mild to moderate and unchanged . Mediastinal and cardiac contours are normal . There is no pneumothorax .
    OUTPUT:
    
1 . Tube and lines are in adequate position . 2 . Slight improvement in right upper lobe opacity . This could reflect improvement of the lung process versus change in ventilation parameters . 3 . Moderate pleural effusions are unchanged .
