Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . The patient 's chin obscures the lung apices . Lordotic positioning of the patient slightly limits assessment . Heart size is moderately enlarged , and accentuated due to low lung volumes . The aorta is calcified and tortuous . Mediastinal contours are unchanged with re - demonstration of rightward deviation of the upper trachea . There is crowding of the bronchovascular structures with possible mild pulmonary vascular congestion , but no overt pulmonary edema . Streaky bibasilar airspace opacities likely reflect atelectasis . No pleural effusion or pneumothorax is seen . The patient is status post vertebroplasty of a lumbar vertebral body . Multilevel degenerative changes are noted in the imaged spine .
    OUTPUT:
    
Low lung volumes with bibasilar atelectasis and possible mild pulmonary vascular congestion .
