Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral chest radiographs demonstrate low lung volumes , resulting in exaggeration of the cardiac silhouette . Allowing for this , the cardiomediastinal silhouette is likely within normal limits . There is no focal consolidation , pleural effusion , or pneumothorax . On lateral view , there are apparent diffuse increased opacities likely related to extremely low lung volumes . The visualized upper abdomen is unremarkable .
    OUTPUT:
    
No acute cardiopulmonary process . Low lung volumes .
