Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . There is moderate cardiomegaly which is relatively unchanged . The aorta is mildly tortuous and diffusely calcified . There is crowding of the bronchovascular structures , with probable mild pulmonary vascular congestion . Streaky right basilar opacity may reflect atelectasis . There is mild attenuation of the pulmonary vascular markings towards the apices suggests underlying emphysema . No large pleural effusion or pneumothorax is seen , with chronic mild pleural thickening at the right costophrenic angle likely indicative of pleural thickening .
    OUTPUT:
    
Low lung volumes with probable mild pulmonary vascular congestion . Right basilar streaky opacity likely reflects atelectasis .
