Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The right mid lung nodular opacity persists , not significantly changed in size since ___ , but new since ___ . The chronic right upper lobe collapse with bronchiectasis demonstrates increased lucency compared with prior . Left mid lung chronic scarring is unchanged . Mediastinal and hilar calcified nodes are consistent with prior granulomatous disease as well as multiple calcified granulomas all of which are unchanged . There has been interval enlargement of the cardiomediastinal silhouette compared with ___ , which could represent cardiomegaly or pericardial effusion . No pleural effusion or pneumothorax is present . Metallic fragments overlying the left ___ and 2nd ribs are unchanged .
    OUTPUT:
    
1 . Persistent right mid lung nodular opacity is not significantly changed from recent CXR ; however , further evaluation by a chest CT is recommended as it was not present on earlier studies . 2 . Increased lucency in chronically collapsed right upper lobe raises the possibility of a chronic cavitary process for which CT would also be helpful to evaluate . 3 . Interval enlargement of the cardiomediastinal silhouette could be related to cardiomegaly or pericardial effusion .
