    INPUT: Lung volumes are low , leading to crowding of the bronchovascular structures . Within this limitation , there is no focal consolidation , pleural effusion , pneumothorax , or pulmonary edema . Allowing for low lung volumes and projection , the cardiac size is top - normal and unchanged from prior examination .
    OUTPUT:
    
Low lung volumes without evidence for acute cardiopulmonary process .
