Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Tracheostomy tube tip terminates approximately 4 .7 cm from the carina . Partially imaged is a catheter within the midline upper abdomen . The heart size is normal . Widening of the left superior mediastinal contour is noted , with slight rightward deviation of the trachea . There is mild pulmonary edema . Lung volumes are low . More focal opacities are noted within the periphery of the right mid and lower lung field as well as left lung base . No large pleural effusion or pneumothorax is present . No acute osseous abnormalities seen .
    OUTPUT:
    
1 . Standard position of the tracheostomy tube . 2 . Mild pulmonary edema . 3 . More focal peripheral opacities within the right mid and lower lung field as well as the left lung base . Findings could reflect areas of infection , and followup radiographs after diuresis are recommended . 4 . Left superior mediastinal widening with mild rightward shift of the trachea . Findings could potentially due to enlarged left thyroid goiter , but other mass lesion is not excluded and further assessment with CT is suggested .
