    INPUT: The inspiratory lung volumes are decreased from the most recent prior chest radiographs . The right hemidiaphragm is elevated , similar to prior CT . There is associated right basilar atelectasis . No significant pleural effusion or pneumothorax is detected . A right - sided Port - A - Cath is seen with the tip terminating in the proximal right atrium . The cardiomediastinal contours are exaggerated due to low lung volumes . Within this limitation , there is no significant change from the prior study allowing for low lung volumes .
    OUTPUT:
    
Low lung volumes with right basilar atelectasis .
