Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , resulting in bronchovascular crowding , but the appearance of the lungs is otherwise unremarkable for supine positioning . Cardiomediastinal and hilar contours are unremarkable . There is no pneumothorax , pleural effusion , or consolidation .
    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 .
