Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Overall increased density of the bilateral lung bases is likely secondary to soft tissue attenuation . No definite confluent consolidation is identified . There is no pulmonary edema or large pleural effusion . No pneumothorax is evident . Mediastinal and hilar contours are within normal limits . Apparent enlargement of the cardiac silhouette is likely exaggerated due to lowe lung volumes . Mild elevation of the left hemidiaphragm appears unchanged from prior . A known cystic lesion within the left lower lobe is not apparent on this radiographic examination .
    OUTPUT:
    
Significant overlying soft tissue attenuation , limiting evaluation , though no definite acute cardiopulmonary process . Lung parenchyma can be more fully evaluated on chest CT which is planned for today .
