The cardiac and mediastinal silhouettes are stable and unremarkable . Surgical clips are seen in the upper abdomen , presumably from prior cholecystectomy .
    OUTPUT:
    
No acute cardiopulmonary process . No significant interval change . If high clinical concern for pneumothorax persists , consider inspiratory and expiratory views .
