Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube is in satisfactory position , within the mid trachea . Enteric tube courses along the esophagus and terminates at the view , likely within the stomach . A left PICC has been removed in the interim . There has been improved aeration of the left lung base , with the left apparent hemidiaphragm being more conspicuous on this exam . Multiple lucenies are also noted in this area . A right hilar opacity is likely infectious in etiology . There is no definite pleural effusion . The right lung is clear and there is no pneumothorax . The cardiomediastinal contours are normal .
    OUTPUT:
    
Slight improvement , albeit persistent , left lower lobe pneumonia . Lucencies in this area may reflect developing cavitation versus newly aerated lung . This could be followed by radiography if the patient is clinically improving , otherwise , a chest CT would be needed for further evaluation .
