No definite focal consolidation is seen . There is no large pleural effusion or pneumothorax . The superior mediastinum is prominent , which may be due to combination of low lung volumes and AP , supine portable technique . However , if there is clinical concern for acute mediastinal process , consider chest CT for further assessment . The cardiac silhouette is top - normal to mildly enlarged , likely artifactually accentuated . No displaced fracture is seen .
