Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral radiographs of the chest demonstrate well expanded , clear lungs . The cardiomediastinal and hilar contours are unremarkable . There is no pneumothorax , pleural effusion , or consolidation . No acute displaced rib fractures are identified .
    OUTPUT:
    
1 . No acute cardiopulmonary process . 2 . 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 .
