Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to the next most recent radiograph of the chest the lungs are similarly expanded . The bandlike opacity in the right upper lobe is not appreciably changed . The cardiomediastinal silhouette is unremarkable without cardiomegaly . The hila are mildly prominent but stable . There is no pleural effusion or pneumothorax . Flowing ossification along the anterior and lateral vertebral bodies is re - demonstrated .
    OUTPUT:
    
1 . Non resolving bandlike opacity in the right upper lobe may represent scarring from prior pneumonia but should be evaluated by non-urgent CT as neoplasm can not be excluded given nonresolution . 2 . Mild prominence of the hila is unchanged suggesting benign etiology though this can be assessed also at time of chest CT . 3 . No evidence of pneumonia .
