Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is not enlarged . The aorta is minimally unfolded . The cardiomediastinal silhouette is otherwise within normal limits . No CHF , focal infiltrate , gross effusion , or pneumothorax is detected . Minimal degenerative change in the thoracic spine could be present . On the available images , there is suggestion of mild right convex curvature in the thoracic spine , but this could be positional . Otherwise , limited assessment of osseous structures is grossly unremarkable . No vertebral body compression or obvious rib fracture is identified . Incidental note is made of nonvisualization of the left clavicular companion shadow .
    OUTPUT:
    
1 . No acute pulmonary process identified . 2 . Possible mild right convex curvature and minimal degenerative changes in the thoracic spine . Limited assessment of osseous structures is otherwise grossly unremarkable . 3 . No free air seen seen beneath the diaphragm . No dilated loops of bowel seen in the visualized portion of the upper abdomen . 4 . Nonvisualization of the left clavicular companion shadow . Clinical correlation to assess for any supraclavicular lymphadenopathy is requested .
