Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . The mediastinal , hilar and cardiac contours appear unchanged . There is persistent relative volume loss in the right hemithorax with opacity about the apex of the right lung suggesting a small pleural effusion . Patchy right basilar opacity suggests atelectasis . Atelectasis is potentially more extensive than explicitly demonstrated noting volume loss and slight rightward shift of mediastinal structures . Partly visualized spinal hardware at the thoracolumbar junction shows no definite change .
    OUTPUT:
    
Persistent right basilar atelectasis and suspected small right pleural effusion .
