Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are relatively low . With this factor in mind , cardiomediastinal contours are within normal limits and without change . Pleural and parenchymal scarring with associated volume loss is present in the right hemithorax , consistent with previous history of partial resection of the right lung , presumably prior right lower lobe resection . No focal areas of consolidation are present , and there are no pleural effusions .
    OUTPUT:
    
1 . No radiographic evidence of pneumonia . 2 . Postoperative scarring and volume loss following partial resection of the right lung .
