Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . There are low lung volumes that accentuate the bronchovascular markings . Left basilar opacity is seen , which could be due to atelectasis , although aspiration or infection is not excluded in the appropriate clinical setting , neither is contusion , although the patient states pain is on the right . No displaced fracture is seen . The aorta is calcified and tortuous . The cardiac silhouette is top normal .
    OUTPUT:
    
Low lung volumes that accentuate the bronchovascular markings . Subtle left basilar opacity may relate to this ; however , underlying atelectasis or even subtle consolidation due to pneumonia or aspiration or even contusion not excluded . No displaced fracture is seen . If high clinical concern for rib fracture , CT or dedicated rib series with BB marker over site of pain , is more sensitive .
