Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are symmetrically well - expanded and well - aerated . Increased density projecting over the right lung base most likely represents superimposition of normal structures including an anterior rib , a posterior rib , and the right nipple . No focal consolidation concerning for pneumonia is detected . There is no significant pleural effusion or pneumothorax . Mild biapical pleural thickening is noted . The pulmonary vasculature is not engorged . The cardiac silhouette is normal in size . The mediastinal and hilar contours are within normal limits . Bilateral pectoral deep brain stimulator devices are in place . No displaced rib are identified . Mild to moderate multilevel degenerative changes of the thoracic spine are re - demonstrated .
    OUTPUT:
    
1 . No displaced rib identified ; however , conventional radiography is limited in sensitivity and , if there is clinical concern , a dedicated rib series should be obtained . 2 . Increased density over the right lung base may represent superimposition of ribs and the right nipple . If there is clinical concern for pneumonia , shallow oblique radiographs could be obtained .
