Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chest AP radiograph demonstrates surgical clips and a draing overlying the right chest wall at the recent operative site . Interval placement of a right - sided drain noted . Ground - glass opacities are present throughout the right lung . These findings in conjunction with an elevated right hemidiaphragm and rightward shift of the mediastinum are suggestive of fibrosis and scarring due to radiation , however , can not definitively excluded an infectious process in the appropriate clinical settings . No pleural effusion or pneumothorax evident . Mediastinal , hilar , and cardiac contours are normal . No osseous abnormality identified .
    OUTPUT:
    
Vague opacity throughout much of the right lung with associated signs of volume loss may indicate scarring , likely due to radiation and overlying soft tissue changes ; however , can not exclude infectious process in the appropriate clinical setting , although doubted within the lungs . No osseous abnormality is identified . For evaluation of operative site , chest CT could be helpful if clinically indicated .
