Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes are present . This accentuates the size of the cardiac silhouette which appears mildly enlarged . Mediastinal contour appears relatively unchanged . Calcified right hilar lymph node seen on previous CT is not well assessed on the current radiograph . Crowding of the bronchovascular structures is present as result of low lung volumes without overt pulmonary edema . Patchy opacities are present within the lung bases which may reflect atelectasis . Previously seen 7 mm right upper lobe nodular opacity is unchanged , and likely reflective of prior granulomatous disease . No focal consolidation , pleural effusion , or pneumothorax is present . Mild degenerative changes are noted within the thoracic spine .
    OUTPUT:
    
Low lung volumes with probable bibasilar atelectasis , though infection is not completely excluded .
