Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardio mediastinal silhouettes are unchanged in appearance . There are increased interstitial opacities bilaterally , however , there is an overall poor inspiratory effort and low lung volumes which limits interpretation , as this may simply be due to crowding of normal vascular structures . It is recommended to repeat radiograph with improved inspiratory effort for better visualization of lung parenchyma . There is loss of definition of the right lateral costophrenic angle which is likely due to small right pleural effusion . There are no pneumothoraces .
    OUTPUT:
    
1 . Limited study due to poor inspiratory effort and low lung volumes with apparent new interstitial process , likely edema . Recommend repeat radiograph with improved inspiration . 2 . Small right pleural effusion .
