Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low which along with AP technique exaggerates the cardiac silhouette which remains normal in size . Mediastinal and hilar contours are unremarkable . Bronchovascular crowding is attributable to low lung volumes without definite vascular congestion or interstitial edema . There is no focal consolidation suggestive of pneumonia . Pleural surfaces are clear without effusion or pneumothorax . Extensive thoracolumbar fixation hardware is incompletely imaged .
    OUTPUT:
    
Low lung volumes without focal consolidation to suggest pneumonia .
