Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is mildly enlarged . The aorta is tortuous . Right hilum remains prominent , compatible with enlargement of the pulmonary artery as seen on the prior CT scan . There is no pulmonary vascular congestion . Bandlike right upper lobe opacity likely reflects subsegmental atelectasis . Additionally , bibasilar streaky opacities likely reflect atelectasis . There is no focal consolidation . No pleural effusion or pneumothorax is seen . There are multilevel degenerative changes in the thoracic spine .
    OUTPUT:
    
1 . Streaky bibasilar and right upper lobe linear opacities likely reflect atelectasis . 2 . Right hilar enlargement likely reflective of pulmonary hypertension , as seen on the prior CT .
