Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Heart size is mildly enlarged . Mediastinal and hilar contours are unremarkable . Diffuse increased interstitial opacities are noted , more pronounced on the left , concerning for chronic interstitial lung disease . More focal opacities in the left lung base and left upper lobe could reflect areas of superimposed contusion , but this is difficult to determine without the presence of prior exams . No pleural effusion or pneumothorax is present . The pulmonary vasculature is not engorged . There are no acute osseous abnormalities . No displaced fractures are visualized .
    OUTPUT:
    
Diffuse bilateral interstitial opacities concerning for chronic interstitial lung disease . Comparison with prior imaging would be helpful to assess whether the more focal opacities in the left upper and lower lobes may reflect areas of superimposed contusion . No acutely displaced fractures identified .
