Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . There is a persistent left lower lobe opacities silhouetting the left hemidiaphragm with elevation of the left hemidiaphragm as before . Likely small left pleural effusion . Unchanged mild cardiomegaly . Endotracheal tube terminates at the thoracic inlet , enteric tube tip terminates in the gastric fundus and EKG leads overlie the chest wall .
    OUTPUT:
    
1 . Endotracheal tube tip terminates at the thoracic inlet . As recommended earlier the tip could be advanced by about 2 cm . 2 . The lung volumes remain low with unchanged left lower lobe atelectasis and elevation of the left hemidiaphragm . 3 . The widened appearance of the mediastinum is likely secondary to the low lung volumes and poor inspiratory effort .
