Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A moderate diffuse interstitial abnormality , more severe in the right lung than the left , is similar in appearance to the prior radiograph . The abnormality is similarly to perhaps slightly more prominent that the prior study , although this may be due to the difference in the penetration of the image . These abnormalities are likely for the most part due to the patient 's underlying chronic interstitial lung disease . There is no definite evidence of pulmonary edema , although small component of new pulmonary edema can not be fully excluded given the very abnormal underlying lung . No focal consolidation is present . No definite pleural effusions are present . There is no pneumothorax . The cardiomediastinal silhouette is normal and unchanged .
    OUTPUT:
    
1 . Asymmetric interstitial lung disease appears similar to perhaps slightly worsened in comparison to prior radiographs . 2 . No definite evidence of pulmonary edema , although the possibility of mild superimposed edema in the background of pre-existing lung disease is difficult to completely exclude . 3 . No definite pneumonia .
