Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: As compared to the prior examination , there has been minimal interval change . Redemonstrated is right - sided volume loss with streaky linear opacities in the right upper lobe which may represent scarring or atelectasis . Similarly , bibasilar streaky opacities likely reflect atelectasis . Pleural thickening is seen at the right lung apex , and pleural calcification is seen adjacent to the right lower lobe . There is no overt pleural effusion , pneumothorax , or pulmonary edema . The aorta is tortuous . The cardiomediastinal silhouette is otherwise stable .
    OUTPUT:
    
1 . Persistent right upper lobe linear opacities , largely unchanged from the prior several examinations . Findings may reflect bronchiectasis , scarring , due to prior tuberculosis or remote necrotizing pneumonia . 2 . Bibasilar atelectasis , right greater than left . 3 . Trachea is not fully imaged on this study . Left lower . Tracheal wall does appear irregular
