Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are well - expanded and clear . Cardiomediastinal hilar contours are unremarkable . There is no pneumothorax , pleural effusion , or consolidation . No acute displaced rib fractures identified .
    OUTPUT:
    
No acute cardiopulmonary process . Although no acute fracture or other chest wall lesion is seen , conventional chest radiographs are not sufficient for detection or characterization of most such abnormalities . If the demonstration of trauma to the chest wall is clinically warranted , the location of any referrable focal findings should be clearly marked and imaged with either bone detail radiographs or Chest CT scanning .
