Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral chest radiographs demonstrate low lung volumes , with increased prominence of the cardiac silhouette and bronchovascular crowding . Even given the low lung volumes , there is at least moderate cardiomegaly . No large focal consolidation , pleural effusion , pneumothorax is seen . In the posterolateral right tenth rib , callus formation is suggestive of a subacute or healed fracture . No acute fracture is identified .
    OUTPUT:
    
1 . No acute fracture identified . Healed posterolateral right tenth rib fracture . 2 . Moderate cardiomegaly , unchanged . Low lung volumes . Although no acute fracture or other chest wall lesion is seen , conventional chest radiographs are not sufficient for detection or characterization of such abnormalities . If the demonstration of a fracture or other trauma is clinically warranted , the location where there are focal findings should be clearly marked and imaged with either bone detail views or CT scanning .
