Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is persistent interstitial lung disease with greatly decreased lung volumes , similar to prior exam . There has been interval increase in reticular opacities in the bilateral lower lobes , with slightly more confluent opacity seen in the left lower lobe . There is no pleural effusion , which suggests the increased reticular opacities are most likely related to interval progression of known pulmonary fibrotic changes . There is no pneumothorax . The cardiomediastinal silhouette is stable .
    OUTPUT:
    
Interval increase in reticular opacities in the bilateral lower lobes , with slightly more confluent opacity seen in the left lower lobe . In the absence of pleural effusion , this most likely represents interval progression of known pulmonary fibrotic changes . If clinical concern for pulmonary edema persists , the patient could be re-imaged after diuresis for further evaluation .
