Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The diaphragms are flattened , suggesting a component of emphysema . A vertical linear abnormality in the medial right upper lung zone is most consistent with bronchiectasis and scarring . Irregular mild linear interstitial opacities in the bilateral bases , right more than left , is most consistent with a chronic interstitial abnormality . There is no focal consolidation to suggest pneumonia . There is no pulmonary edema . Small bilateral pleural effusions are noted , left more than right . There is no pneumothorax . The cardiomediastinal silhouette is normal .
    OUTPUT:
    
1 . No evidence of pneumonia . 2 . Probable chronic interstitial abnormality in the base , as well as right upper lobe bronchiectasis and scarring . If further characterization of these abnormalities is needed , a CT of the chest could be obtained . 3 . Small bilateral pleural effusions .
