Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are lower compared to the prior study . This accentuates the size of the cardiac silhouette which is likely mildly enlarged . The aorta is slightly tortuous . There is crowding of the bronchovascular structures , with mild possible mild pulmonary vascular engorgement likely present . Diffuse calcified pleural plaques limits assessment of the pulmonary parenchyma . There are likely patchy opacities in the lung bases reflective of atelectasis . Minimal blunting of the right costophrenic angle appears new compared to the prior study and may be due to a small pleural effusion . No pneumothorax is identified . No acute osseous abnormalities seen .
    OUTPUT:
    
1 . Bilateral calcified pleural plaques compatible with prior asbestos exposure . 2 . Low lung volumes with probable bibasilar atelectasis and possible mild pulmonary vascular congestion . Blunting of the right costophrenic angle suggests a trace pleural effusion .
