Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chronic appearing changes are noted at the right lung with chronic volume loss . There is chronic blunting of the right costophrenic angle which may be due to small pleural effusion or pleural thickening . Subtle increase in interstitial markings bilaterally may be due to minimal interstitial edema superimposed on COPD . No lobar consolidation . No pneumothorax . Cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
Chronic volume loss of the right lung compared to the left . Chronic blunting of the right costophrenic angle , trace pleural effusion versus pleural thickening . Subtle increase in interstitial markings diffusely bilaterally may be due to minimal interstitial edema superimposed on COPD . No lobar consolidation . If high clinical concern for mediastinal or hilar adenopathy , CT is more sensitive and should be considered .
