Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . The heart size is mildly enlarged with left ventricular predominance . The aorta is tortuous . There is crowding of the bronchovascular structures without overt pulmonary edema . Patchy opacities in the lung bases , more pronounced on the right likely reflect areas of atelectasis . No focal consolidation , pleural effusion or pneumothorax is identified . Degenerative changes are again seen in the thoracic spine with mild loss of height of several vertebral bodies , grossly unchanged .
    OUTPUT:
    
Low lung volumes . Patchy bibasilar airspace opacities , more pronounced on the right , likely reflect areas of atelectasis . Please note infection can not be completely excluded , and consider repeat radiographs with improved inspiratory effort for better assessment of the lung bases .
