Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hyperinflated with flattening of the hemidiaphragms , most consistent with emphysema . Basilar linear opacities are not significantly changed from the prior exam , likely representing chronic atelectasis . There is no new consolidation , pulmonary edema , pleural effusion , or pneumothorax . There is pleural thickening at the bases and apices . The cardiomediastinal silhouette is unchanged . Again , the aorta is tortuous and diffusely calcified . The heart is minimally enlarged .
    OUTPUT:
    
Stable emphysema and basilar opacities , which are likely atelectasis . No acute cardiopulmonary process .
