Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The inspiratory lung volumes are decreased with resultant bronchovascular crowding . Within this limitation , no large pleural effusion , focal consolidation or pneumothorax is detected . The pulmonary vasculature is slightly prominent , most likely related to low lung volumes , but mild vascular engorgement could be present . The cardiomediastinal contours are within normal limits . Tortuosity of the thoracic aorta is unchanged . A compression fracture deformity at the upper lumbar spine is unchanged from ___ .
    OUTPUT:
    
Low lung volumes and possible minimal pulmonary vascular congestion . Unchanged compression fracture deformity of the upper lumbar spine from ___ .
