Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lateral view shows a nondisplaced fracture of the mid portion of the sternal body , with a modest amount of presternal and retrosternal bleeding . No displaced rib fracture is seen , but since the conventional chest radiograph is not sensitive in detecting subtle chest cage trauma , the subsequent chest CT scan should be consulted . Sternal fracture is associated with hemopericardium and cardiac trauma and should be evaluated clinically and with appropriate imaging . Severe bullous emphysema is chronic . Bands of atelectasis or scarring involving several bulla also are stable dating back to ___ . Lower lung volumes are probably a reflection of splinting and would explain the relative increase in ___ in both lower lung zones compared to ___ . This includes partial obliteration of the left cardiac border , but there is the possibility of some a lung contusion particularly in the lingula , and a smaller region in the axillary sub segments of the right upper lobe projecting over the third anterior interspace , also best evaluated on the chest CT . There is no pleural effusion or pneumothorax
    OUTPUT:
    
1 . No evidence of rib fracture . 2 . Nondisplaced sternal fracture .
