Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Heart size is accentuated as a result and appears mildly enlarged . The mediastinal and hilar contours are within normal limits . There is no pulmonary edema , focal consolidation , pleural effusion or pneumothorax . Patchy opacities are seen in the lung bases which may reflect areas of atelectasis . No acute osseous abnormality is detected . Mild degenerative changes are noted in the imaged thoracolumbar spine .
    OUTPUT:
    
Low lung volumes with bibasilar patchy opacities at the lung bases likely reflective of atelectasis . Infection can not be completely excluded , however , and consider a follow - up PA and lateral view of the chest with improved inspiratory when the patient is able to do so .
