Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are clear without focal consolidation , pleural effusion or pneumothorax . There is no pulmonary edema . The heart is normal in size , and the mediastinal contours are normal . No displaced rib fractures are noted . 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 .
    OUTPUT:
    
No acute cardiopulmonary process .
