Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is at the upper limits of normal size with mild unfolding of the thoracic aorta . Within the limitations of technique , the mediastinal contours appear mildly widened along the right upper portion , although likely within normal limits . There is no definite pleural effusion or pneumothorax . Mild peripheral reticulation suggests some background interstitial changes . A thin anterior flowing syndesmophyte courses throughout the visualized thoracic spine suggesting hyperostosis . The bones are probably demineralized .
    OUTPUT:
    
1 . No definite evidence of injury . 2 . Findings suggesting mild interstitial changes in the lungs . 3 . Apparent widening of the right upper mediastinal contour , although probably technique - related . Comparison to prior radiographs is suggested as well as acquisition of standard PA and lateral views , when clinically appropriate .
