Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A Port - A - Cath terminates in the upper right atrium , as before . The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There is no pleural effusion or pneumothorax . Moderate relative elevation of the right hemidiaphragm appears similar . There is blunting of the right costophrenic sulcus which appears unchanged . Correlating with the recent prior CT , there has been no definite change and this appearance seems to be due to scarring in the costophrenic sulcus rather than a pleural effusion . The lungs appear clear . Surgical clips project about the epigastrium . The bony structures are unremarkable .
    OUTPUT:
    
No evidence of acute disease .
