Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Similarly to the prior chest radiograph , lung volumes are low , causing crowding of the bronchovascular structures . The previously described right middle lobe heterogeneous opacity has improved . Mild basilar streaky opacifications are likely due to atelectasis . No new focal consolidation or pneumothorax . Mild blunting of the bilateral costophrenic angles are consistent with small pleural effusions .
    OUTPUT:
    
1 . Low lung volumes , causing crowding of bronchovascular structures . Previously described right middle lobe opacity has improved . 2 . No new focal consolidation or pneumothorax . Likely bibasilar streaky atelectasis . 3 . Small bilateral effusions .
